* fix-2360: prevent asyncio CPU spin loop after SSE client disconnect

Root cause: Fire-and-forget asyncio.create_task() patterns left orphaned
tasks that caused anyio _deliver_cancellation to spin at 100% CPU per worker.

Changes:
- Add _respond_tasks dict to track respond tasks by session_id
- Cancel respond tasks explicitly before session cleanup in remove_session()
- Cancel all respond tasks during shutdown()
- Pass disconnect callback to SSE transport for defensive cleanup
- Convert database backend from fire-and-forget to structured concurrency

The fix ensures all asyncio tasks are properly tracked, cancelled on disconnect,
and awaited to completion, preventing orphaned tasks from spinning the event loop.

Closes IBM#2360

* fix-2360: additional fixes for CPU spin loop after SSE disconnect

Follow-up fixes based on testing and review:

1. Cancellation timeout escalation (Finding 1):
   - _cancel_respond_task() now escalates on timeout by calling transport.disconnect()
   - Retries cancellation after escalation
   - Always removes task from tracking to prevent buildup

2. Redis respond loop exit path (Finding 2):
   - Changed from infinite pubsub.listen() to timeout-based get_message() polling
   - Added session existence check - loop exits if session removed
   - Allows loop to exit even without cancellation

3. Generator finally block cleanup (Finding 3):
   - Added on_disconnect_callback() in event_generator() finally block
   - Covers: CancelledError, GeneratorExit, exceptions, and normal completion
   - Idempotent - safe if callback already ran from on_client_close

4. Added load-test-spin-detector make target:
   - Spike/drop pattern to stress test session cleanup
   - Docker stats monitoring at each phase
   - Color-coded output with pass/fail indicators
   - Log file output to /tmp

* fix-2360: fix race condition in sse_endpoint and add stuck task tracking

Finding 1 (HIGH): Fixed race condition in sse_endpoint where respond task
was created AFTER create_sse_response(). If client disconnected during
response setup, the disconnect callback ran before the task existed,
leaving it orphaned. Now matches utility_sse_endpoint ordering:
1. Compute user_with_token
2. Create and register respond task
3. Call create_sse_response()

Finding 2 (MEDIUM): Added _stuck_tasks dict to track tasks that couldn't
be cancelled after escalation. Previously these were dropped from tracking
entirely, losing visibility. Now they're moved to _stuck_tasks for
monitoring and final cleanup during shutdown().

Updated tests to verify escalation behavior.

* fix-2360: add SSE failure cleanup, stuck task reaper, and full load test

Finding 1 (HIGH): Fixed orphaned respond task when create_sse_response()
fails. Added try/except around create_sse_response() in both sse_endpoint
and utility_sse_endpoint - on failure, calls remove_session() to clean up
the task and session before re-raising.

Finding 2 (MEDIUM): Added stuck task reaper that runs every 30 seconds to:
- Remove completed tasks from _stuck_tasks
- Retry cancellation for still-stuck tasks
- Prevent memory leaks from tasks that eventually complete

Finding 3 (LOW): Added test for escalation path with fake transport to
verify transport.disconnect() is called during escalation. Also added
tests for the stuck task reaper lifecycle.

Also updated load-test-spin-detector to be a full-featured test matching
load-test-ui with JWT auth, all user classes, entity ID fetching, and
the same 4000-user baseline.

* fix-2360: improve load-test-spin-detector output and reduce cycle sizes

- Reduce logging level to WARNING to suppress noisy worker messages
- Only run entity fetching and cleanup on master/standalone nodes
- Reduce cycle sizes from 4000 to 1000 peak users for faster iteration
- Update banner to reflect new cycle pattern (500 -> 750 -> 1000)
- Remove verbose JWT token generation log

* fix-2360: address remaining CPU spin loop findings

Finding 1 (HIGH): Add explicit asyncio.CancelledError handling in SSE
endpoints. In Python 3.8+, CancelledError inherits from BaseException,
not Exception, so the previous except block wouldn't catch it. Now
cleanup runs even when requests are cancelled during SSE handshake.

Finding 2 (MEDIUM): Add sleep(0.1) when Redis get_message returns None
to prevent tight loop. The loop now has guaranteed minimum sleep even
when Redis returns immediately in certain states.

Finding 3 (MEDIUM): Add _closing_sessions set to allow respond loops
to exit early. remove_session() now marks the session as closing BEFORE
attempting task cancellation, so the respond loop (Redis and DB backends)
can exit immediately without waiting for the full cancellation timeout.

Finding 4 (LOW): Already addressed in previous commit with test
test_cancel_respond_task_escalation_calls_transport_disconnect.

* fix(pubsub): replace blocking listen() with timeout-based get_message()

The blocking `async for message in pubsub.listen()` pattern doesn't
respond to asyncio cancellation properly. When anyio's cancel scope
tries to cancel tasks using this pattern, the tasks don't respond
because the async iterator is blocked waiting for Redis messages.

This causes anyio's `_deliver_cancellation` to continuously reschedule
itself with `call_soon()`, creating a CPU spin loop that consumes
100% CPU per affected worker.

Changed to timeout-based polling pattern:
- Use `get_message(timeout=1.0)` with `asyncio.wait_for()`
- Loop allows cancellation check every ~1 second
- Added sleep on None/non-message responses to prevent edge case spins

Files fixed:
- mcpgateway/services/cancellation_service.py
- mcpgateway/services/event_service.py

Closes IBM#2360 (partial - additional spin sources may exist)

* fix(cleanup): add timeouts to __aexit__ calls to prevent CPU spin loops

The MCP session/transport __aexit__ methods can block indefinitely when
internal tasks don't respond to cancellation. This causes anyio's
_deliver_cancellation to spin in a tight loop, consuming ~800% CPU.

Root cause: When calling session.__aexit__() or transport.__aexit__(),
they attempt to cancel internal tasks (like post_writer waiting on
memory streams). If these tasks don't respond to CancelledError, anyio's
cancel scope keeps calling call_soon() to reschedule _deliver_cancellation,
creating a CPU spin loop.

Changes:
- Add SESSION_CLEANUP_TIMEOUT constant (5 seconds) to mcp_session_pool.py
- Wrap all __aexit__ calls in asyncio.wait_for() with timeout
- Add timeout to pubsub cleanup in session_registry.py and registry_cache.py
- Add timeout to streamable HTTP context cleanup in translate.py

This is a continuation of the fix for issue IBM#2360.

Signed-off-by: Mihai Criveti <crivetimihai@gmail.com>

* feat(config): make session cleanup timeout configurable

Add MCP_SESSION_POOL_CLEANUP_TIMEOUT setting (default: 5.0 seconds) to
control how long cleanup operations wait for session/transport __aexit__
calls to complete.

Clarification: This timeout does NOT affect tool execution time (which
uses TOOL_TIMEOUT). It only affects cleanup of idle/released sessions
to prevent CPU spin loops when internal tasks don't respond to cancel.

Changes:
- Add mcp_session_pool_cleanup_timeout to config.py
- Add MCP_SESSION_POOL_CLEANUP_TIMEOUT to .env.example with docs
- Add to charts/mcp-stack/values.yaml
- Update mcp_session_pool.py to use _get_cleanup_timeout() helper
- Update session_registry.py and registry_cache.py to use config
- Update translate.py to use config with fallback

When to adjust:
- Increase if you see frequent "cleanup timed out" warnings in logs
- Decrease for faster shutdown (at risk of resource leaks)

* fix(sse): add deadline to cancel scope to prevent CPU spin loop

Fixes CPU spin loop (anyio#695) where _deliver_cancellation spins at
100% CPU when SSE task group tasks don't respond to cancellation.

Root cause: When an SSE connection ends, sse_starlette's task group
tries to cancel all tasks. If a task (like _listen_for_disconnect
waiting on receive()) doesn't respond to cancellation, anyio's
_deliver_cancellation keeps rescheduling itself in a tight loop.

Fix: Override EventSourceResponse.__call__ to set a deadline on the
cancel scope when cancellation starts. This ensures that if tasks
don't respond within SSE_TASK_GROUP_CLEANUP_TIMEOUT (5 seconds),
the scope times out instead of spinning indefinitely.

* fix(translate): use patched EventSourceResponse to prevent CPU spin

translate.py was importing EventSourceResponse directly from sse_starlette,
bypassing the patched version in sse_transport.py that prevents the anyio
_deliver_cancellation CPU spin loop (anyio#695).

This change ensures all SSE connections in the translate module (stdio-to-SSE
bridge) also benefit from the cancel scope deadline fix.

* fix(cleanup): reduce cleanup timeouts from 5s to 0.5s

With many concurrent connections (691 TCP sockets observed), each cancelled
SSE task group spinning for up to 5 seconds caused sustained high CPU usage.
Reducing the timeout to 0.5s minimizes CPU waste during spin loops while
still allowing normal cleanup to complete.

The cleanup timeout only affects cleanup of cancelled/released connections,
not normal operation or tool execution time.

Changes:
- SSE_TASK_GROUP_CLEANUP_TIMEOUT: 5.0 -> 0.5 seconds
- mcp_session_pool_cleanup_timeout: 5.0 -> 0.5 seconds
- Updated .env.example and charts/mcp-stack/values.yaml

- Keep MCP_SESSION_POOL_CLEANUP_TIMEOUT at 5.0s default
- Override both to 0.5s in docker-compose.yml for testing

The 5.0s default is safe for production. The 0.5s override in
docker-compose.yml allows testing aggressive cleanup to verify
it doesn't affect normal operation.

* fix(gunicorn): reduce max_requests to recycle stuck workers

The MCP SDK's internal anyio task groups don't respond to cancellation
properly, causing CPU spin loops in _deliver_cancellation. This spin
happens inside the MCP SDK (streamablehttp_client, sse_client) which
we cannot patch.

Reduce GUNICORN_MAX_REQUESTS from 10M to 5K to ensure workers are
recycled frequently, cleaning up any accumulated stuck task groups.

Root cause chain observed:
1. PostgreSQL idle transaction timeout
2. Gateway state change failures
3. SSE connections terminated
4. MCP SDK task groups spin (anyio#695)

This is a workaround until the MCP SDK properly handles cancellation.

* fix(anyio): monkey-patch _deliver_cancellation to prevent CPU spin

Root cause: anyio's _deliver_cancellation has no iteration limit.
When tasks don't respond to CancelledError, it schedules call_soon()
callbacks indefinitely, causing 100% CPU spin (anyio#695).

Solution:
- Monkey-patch CancelScope._deliver_cancellation to track iterations
- Give up after 100 iterations and log warning
- Clear _cancel_handle to stop further call_soon() callbacks

Also switched from asyncio.wait_for() to anyio.move_on_after() for
MCP session cleanup, which better propagates cancellation through
anyio's cancel scope system.

Trade-off: If cancellation gives up after 100 iterations, some tasks
may not be properly cancelled. However, GUNICORN_MAX_REQUESTS=5000
worker recycling will eventually clean up orphaned tasks.

* fix(transport): support mixed content types from MCP server tool call response

Closes IBM#2512

This fix addresses tool invocation failures for tools that return complex
content types (like ResourceLink, ImageContent, AudioContent) or contain
Pydantic-specific types like AnyUrl.

Root causes fixed:
1. tool_service.py: Usage of model_dump() without mode='json' preserved
   pydantic.AnyUrl objects, violating internal model's str type constraints.
2. streamablehttp_transport.py: Code blindly assumed types.TextContent,
   accessing .text on every item, which crashed for ResourceLink or ImageContent.

Changes:
- Updated tool_service.py to use model_dump(by_alias=True, mode='json'),
  forcing conversion of AnyUrl to JSON-compatible strings.
- Refactored streamablehttp_transport.py to inspect content.type and correctly
  map to proper MCP SDK types (TextContent, ImageContent, AudioContent,
  ResourceLink, EmbeddedResource) ensuring full protocol compatibility.
- Updated return type annotation to include all MCP content types.

* fix(db): release DB sessions before external HTTP calls to prevent pool exhaustion

This commit addresses issue IBM#2518 where DB connection pool exhaustion occurred
during A2A and RPC tool calls due to sessions being held during slow upstream
HTTP requests.

Changes:
- tool_service.py: Extract A2A agent data to local variables before calling
  db.commit(), allowing HTTP calls to proceed without holding the DB session.
  The A2A tool invocation logic now uses pre-extracted data instead of querying
  during the HTTP call phase.

- rbac.py: Add db.commit() and db.close() calls before returning user context
  in all authentication paths (proxy, anonymous, disabled auth). This ensures
  DB sessions are released early and not held during subsequent request processing.

- test_rbac.py: Update test to provide mock db parameter and verify that
  db.commit() and db.close() are called for proper session cleanup.

The fix follows the pattern established in other services: extract all needed
data from ORM objects, call db.commit() to release the transaction, then
proceed with external HTTP calls. This prevents "idle in transaction" states
that exhaust PgBouncer's connection pool under high load.

Load test results (4000 concurrent users, 1M+ requests):
- Success rate: 99.81%
- 502 errors reduced to 0.02% (edge cases with very slow upstreams)

…BM#2534)

The MCP specification does not mandate that tool names must start with
a letter - tool names are simply strings without pattern restrictions.
This fix updates the validation pattern to align with SEP-986.

Changes:
- Update VALIDATION_TOOL_NAME_PATTERN from ^[a-zA-Z][a-zA-Z0-9._-]*$
  to ^[a-zA-Z0-9_][a-zA-Z0-9._/-]*$ per SEP-986
- Allow leading underscore/number and slashes in tool names
- Remove / from HTML special characters regex (not XSS-relevant)
- Update all error messages, docstrings, and documentation
- Update tests to verify new valid cases

Tool names like `_5gpt_query_by_market_id` and `namespace/tool` are
now accepted.

Fixes: IBM#1938

This commit addresses an issue where admin metrics were empty during
benchmark tests shorter than one hour because they relied on hourly
rollup jobs. The metrics query service is updated to use a three-source
aggregation:

1. Historical rollups (for data older than the retention period)
2. Raw metrics for completed hours within the retention period
3. Raw metrics from the current, incomplete hour

This ensures that metrics are always up-to-date, even before the hourly
rollup job runs, providing immediate visibility and preventing expensive
raw table scans during short-lived tests.

Test improvements:
- Fix flaky test at hour boundary (race condition)
- Remove unused patch import
- Add tests for three-source merge behavior

* fix: prevent ReDoS in SSTI validation patterns

Replace regex-based SSTI detection with a linear-time manual parser
to eliminate ReDoS vulnerability while improving bypass resistance.

Changes:
- Add _iter_template_expressions() parser that correctly handles:
  - Quoted strings (single and double quotes)
  - Escaped characters within strings
  - Nested delimiters inside quotes (e.g., "}}" in strings)
  - Continues scanning after unterminated expressions (fail-closed)
- Replace _SSTI_PATTERNS regex list with:
  - _SSTI_DANGEROUS_SUBSTRINGS tuple for keyword detection
  - _SSTI_DANGEROUS_OPERATORS tuple for arithmetic in {{ }} and {% %}
  - _SSTI_SIMPLE_TEMPLATE_PREFIXES for ${, #{, %{ expressions
- Add _has_simple_template_expression() with O(n) linear scan using rfind
- Fix type annotation for validate_parameter_length()
- Block dynamic attribute access bypasses:
  - |attr filter for dynamic attribute access (with whitespace normalization)
  - |selectattr, |sort, |map filters (can take attribute names)
  - getattr function
  - ~ operator for string concatenation (dunder name construction)
  - [ bracket notation for dynamic access
  - % operator for string formatting (e.g., '%c' % 95)
  - attribute= parameter (blocks map/selectattr/sort attribute access)
  - All escape sequences: \x, \u, \N{, \0-\7 (octal)
- Apply operator checks to both {{ }} and {% %} blocks
- Normalize whitespace around | and = before checking

Performance:
- O(n) linear scanning eliminates catastrophic backtracking
- _has_simple_template_expression uses rfind for O(n) instead of O(n²)

Security:
- Proper quote handling blocks bypasses like {{ "}}" ~ self.__class__ }}
- Escaped quote handling blocks {{ "a\"}}b" ~ self }} bypasses
- Blocks dynamic construction bypasses via string concatenation
- Blocks all escape sequence bypasses (hex, unicode, octal)
- Blocks whitespace-based bypasses around | and =
- Blocks % formatting bypasses (e.g., '%c%c' % (95,95))
- Fail-closed: continues scanning after unterminated expressions

Tests:
- Add comprehensive SSTI bypass test cases
- Add pytest.mark.timeout(30) for deterministic ReDoS detection
- Add pathological input tests for ReDoS prevention verification

…IBM#2569)

Implement strict per-tool timeout enforcement for all transports
(REST, SSE, StreamableHTTP, A2A) and enhance the CircuitBreakerPlugin
with half-open states, retry headers, and granular configuration.

Changes:
- Wrap all tool invocations in asyncio.wait_for with effective_timeout
- Add per-tool timeout_ms support (ms to seconds conversion)
- Add half-open state for circuit breaker recovery testing
- Add half_open_in_flight flag to prevent concurrent probe requests
- Add retry_after_seconds in violation response for rate limiting
- Add tool_timeout_total and circuit_breaker_open_total Prometheus metrics
- Add cb_timeout_failure context flag for timeout detection in plugins
- Add tool_overrides for per-tool circuit breaker configuration
- Handle both asyncio.TimeoutError and httpx.TimeoutException
- Log actual elapsed time instead of configured timeout

Fixes applied during review:
- Fix _is_error() to detect camelCase isError from model_dump(by_alias=True)
- Fix half-open probe guard: only check when st.half_open is True
- Add stale-probe timeout to prevent permanent wedge if plugin blocks
- Add timeout enforcement to A2A tool invocations
- Call tool_post_invoke on exceptions so circuit breaker tracks failures
- Add ToolTimeoutError subclass to distinguish timeouts from other errors
- Only skip post_invoke for ToolTimeoutError (not all ToolInvocationError)
- Set error_message and span attributes for ToolTimeoutError observability
- Update README to document isError camelCase support

Timeout precedence:
1. Per-tool timeout_ms (if set and non-zero)
2. Global TOOL_TIMEOUT setting (default: 60s)

…BM#2549)

Replace long-lived database sessions in RBAC middleware with
fresh_db_session() context manager to prevent session accumulation
under high concurrent load.

Changes:
- Remove db parameter from get_current_user_with_permissions()
- Use fresh_db_session() context manager for short-lived DB access
- Keep "db": None in user context for backward compatibility
- Add deprecation warnings to get_db() and get_permission_service()
- Update all permission decorators to use fresh_db_session() fallback
- Update PermissionChecker to use fresh_db_session() pattern
- Simplify db.py by reusing get_db() generator for fresh_db_session

Security fixes:
- Use named kwargs (user, _user, current_user, current_user_ctx) for
  user context extraction instead of scanning all dicts for "email"
  to prevent request body injection attacks

Performance fixes:
- PermissionChecker.has_any_permission now uses single session for
  all permission checks instead of opening N sessions

This prevents idle-in-transaction bottlenecks where sessions were
held for entire request duration instead of milliseconds.

  tool_pre_invoke and resource_pre_fetch
- plugins/unified_pdp/pdp.py          — PolicyDecisionPoint orchestrator
- plugins/unified_pdp/pdp_models.py   — Pydantic models (Subject, Resource,
  Context, AccessDecision, config types)
- plugins/unified_pdp/adapter.py      — Abstract engine adapter base class
- plugins/unified_pdp/cache.py        — TTL-aware decision cache
- plugins/unified_pdp/engines/        — Four engine adapters: native_engine,
  mac_engine, opa_engine, cedar_engine
- plugins/unified_pdp/default_rules.json — Starter RBAC ruleset
- tests/unit/plugins/test_unified_pdp.py — 46 unit tests
- plugins/config.yaml                 — Plugin registration (mode: disabled)
- MANIFEST.in                         — Added recursive-include plugins *.json

* feat(gateway): add configurable URL validation for gateway endpoints

Add comprehensive URL validation with configurable network access controls
for gateway and tool URL endpoints. This allows operators to control which
network ranges are accessible based on their deployment environment.

New configuration options:
- SSRF_PROTECTION_ENABLED: Master switch for URL validation (default: true)
- SSRF_ALLOW_LOCALHOST: Allow localhost/loopback (default: true for dev)
- SSRF_ALLOW_PRIVATE_NETWORKS: Allow RFC 1918 ranges (default: true)
- SSRF_DNS_FAIL_CLOSED: Reject unresolvable hostnames (default: false)
- SSRF_BLOCKED_NETWORKS: CIDR ranges to always block
- SSRF_BLOCKED_HOSTS: Hostnames to always block

Features:
- Validates all resolved IP addresses (A and AAAA records)
- Normalizes hostnames (case-insensitive, trailing dot handling)
- Blocks cloud metadata endpoints by default (169.254.169.254, etc.)
- Dev-friendly defaults with strict mode available for production
- Full documentation and Helm chart support

Also includes minor admin UI formatting improvements.

* feat(auth): add token-scoped filtering for list endpoints and gateway forwarding

- Add token_teams parameter to list_servers and list_gateways endpoints
  for proper scoping based on JWT token team claims
- Update server_service.list_servers() and gateway_service.list_gateways()
  to filter results by token scope (public-only, team-scoped, or unrestricted)
- Skip caching for token-scoped queries to prevent cross-user data leakage
- Update gateway forwarding (_forward_request_to_all) to respect token team scope
- Fix public-only token handling in create endpoints (tools, resources, prompts,
  servers, gateways, A2A agents) to reject team/private visibility
- Preserve None vs [] distinction in SSE/WebSocket for proper admin bypass
- Update get_team_from_token to distinguish missing teams (legacy fallback)
  from explicit empty teams (public-only access)
- Add request.state.token_teams storage in all auth paths for downstream access

* feat(auth): add normalize_token_teams for consistent token scoping

Introduces a centralized `normalize_token_teams()` function in auth.py
that provides consistent token team normalization across all code paths:

- Missing teams key → empty list (public-only access)
- Explicit null teams + admin flag → None (admin bypass)
- Explicit null teams without admin → empty list (public-only)
- Empty teams array → empty list (public-only)
- Team list → normalized string IDs (team-scoped)

Additional changes:
- Update _get_token_teams_from_request() to use normalized teams
- Fix caching in server/gateway services to only cache public-only queries
- Fix server creation visibility parameter precedence
- Update token_scoping middleware to use normalize_token_teams()
- Add comprehensive unit tests for token normalization behavior

* feat(websocket): forward auth credentials to /rpc endpoint

The WebSocket /ws endpoint now propagates authentication credentials
when making internal requests to /rpc:

- Forward JWT token as Authorization header when present
- Forward proxy user header when trust_proxy_auth is enabled
- Enables WebSocket transport to work with AUTH_REQUIRED=true

Also adds unit tests to verify auth credential forwarding behavior.

* feat(rbac): add granular permission checks to all admin routes

- Add @require_permission decorators to all 177 admin routes with
  allow_admin_bypass=False to enforce explicit permission checks
- Add allow_admin_bypass parameter to require_permission and
  require_any_permission decorators for configurable admin bypass
- Add has_admin_permission() method to PermissionService for checking
  admin-level access (is_admin, *, or admin.* permissions)
- Update AdminAuthMiddleware to use has_admin_permission() for
  coarse-grained admin UI access control
- Create shared test fixtures in tests/unit/mcpgateway/conftest.py
  for mocking PermissionService across unit tests
- Update test files to use proper user context dict format

* fix(rbac): add explicit db dependency to RBAC-protected routes

Address load test findings from RCA #1 and IBM#2:

- Add `db: Session = Depends(get_db)` to routes in email_auth.py,
  llm_config_router.py, and teams.py that use @require_permission
- Fix test files to pass mock_db parameter after signature changes
- Add shm_size: 256m to PostgreSQL in docker-compose.yml
- Remove non-serializable content from resource update events
- Disable CircuitBreaker plugin for consistent load testing

These changes fix the NoneType errors (~33,700) observed under 4000
concurrent users where current_user_ctx["db"] was always None.

Remaining critical issue: Transaction leak in streamablehttp_transport.py
causing idle-in-transaction connections (see todo/rca2.md for details).

* fix(db): resolve transaction leak and connection pool exhaustion

Critical fixes for load test failures at 4000 concurrent users:

Issue #1 - Transaction leak in streamablehttp_transport.py (CRITICAL):
- Add explicit asyncio.CancelledError handling in get_db() context manager
- When MCP handlers are cancelled (client disconnect, timeout), the finally
  block may not execute properly, leaving transactions "idle in transaction"
- Now explicitly rollback and close before re-raising CancelledError
- Add rollback in direct SessionLocal usage at line ~1425

Issue IBM#2 - Missing db parameter in admin routes (HIGH):
- Add `db: Session = Depends(get_db)` to 73 remaining admin routes
- Routes with @require_permission but no db param caused decorator to
  create fresh session via fresh_db_session() for EVERY permission check
- This doubled connection usage for affected routes under load

Issue IBM#3 - Slow recovery from transaction leaks (MEDIUM):
- Reduce IDLE_TRANSACTION_TIMEOUT from 300s to 30s in docker-compose.yml
- Reduce CLIENT_IDLE_TIMEOUT from 300s to 60s
- Leaked transactions now killed faster, preventing pool exhaustion

Root cause confirmed: list_resources() MCP handler was primary source,
with 155+ connections stuck on `SELECT resources.*` for up to 273 seconds.

See todo/rca2.md for full analysis including live test data showing
connection leak progression and 606+ idle transaction timeout errors.

* fix(teams): use consistent user context format across all endpoints

- Update request_to_join_team and leave_team to use dict-based user context
- Fix teams router to use get_current_user_with_permissions consistently
- Move /discover route before /{team_id} to prevent route shadowing
- Update test fixtures to use mock_user_context dict format
- Add transaction commits in resource_service to prevent connection leaks
- Add missing docstring parameters for flake8 compliance

* fix(db): add explicit db.commit/close to prevent transaction leaks

Add explicit db.commit(); db.close() calls to 100+ endpoints across
all routers to prevent PostgreSQL connection leaks under high load.

Problem: Under high concurrency, FastAPI's Depends(get_db) cleanup
runs after response serialization, causing transactions to remain
in 'idle in transaction' state for 20-30+ seconds, exhausting the
connection pool.

Solution: Explicitly commit and close database sessions immediately
after database operations complete, before response serialization.

Routers fixed:
- tokens.py: 10 endpoints (create, list, get, update, revoke, usage, admin, team tokens)
- llm_config_router.py: 14 endpoints (provider/model CRUD, health, gateway models)
- sso.py: 5 endpoints (SSO provider CRUD)
- email_auth.py: 3 endpoints (user create/update/delete)
- oauth_router.py: 1 endpoint (delete_registered_client)
- teams.py: 18 endpoints (team CRUD, members, invitations, join requests)
- rbac.py: 12 endpoints (roles, user roles, permissions)
- main.py: 14 CUD + 3 list + 7 RPC handlers

Also fixes:
- admin.py: Rename 21 unused db params to _db (pylint W0613)
- test_teams*.py: Add mock_db fixture to tests calling router functions directly
- Add llms/audit-db-transaction-management.md for future audits

* fix(rpc): fix list_gateways tuple unpacking and add token scoping

The RPC list_gateways handler had two bugs:
1. Did not unpack the tuple (gateways, next_cursor) returned by
   gateway_service.list_gateways(), causing 'list' object has no
   attribute 'model_dump' error
2. Was missing token scoping via _get_rpc_filter_context(), which
   was the original R-02 security fix

Also fixed all callers of list_gateways that expected a list but
now receive a tuple:
- mcpgateway/admin.py: get_gateways_section()
- mcpgateway/services/import_service.py: 3 call sites

Updated test mocks to return (list, None) tuples instead of lists.

* fix(teams): build response before db.close() to avoid lazy-load errors

The teams router was calling db.commit(); db.close() before building
the TeamResponse, but TeamResponse includes team.get_member_count()
which needs an active session. When the session is closed, the fallback
in get_member_count() tries to access self.members (lazy-loaded),
causing "Parent instance is not bound to a Session" errors.

Fixed by building TeamResponse BEFORE calling db.close() in:
- create_team
- get_team
- update_team

* fix(teams): fix update_team expecting team object but getting bool

The service's update_team() returns bool, but the router was treating
the return value as a team object and trying to access .id, .name, etc.

Fixed by:
1. Checking the boolean return value for success
2. Fetching the team again after successful update to build the response

* fix(teams): fix update_member_role return type mismatch

The service's update_member_role() returns bool, but the router
treated it as a member object. Fixed by:
1. Checking the boolean success
2. Added get_member() method to TeamManagementService
3. Fetching the updated member to build the response
