…y trace plan support

Default trace collector: add ErrorLog, Object DDL, Security Audit event types;
add duration_us and end_time columns for autogrow I/O stall tracking;
filter autogrow to > 1s duration only; exclude tempdb Object DDL and auto-stats (_WA_%).
Remove redundant Trace Analysis tab (superseded by Query Trace Patterns).

Dashboard memory clerks: add type picker with search, top-N, select/clear-all
(parity with Lite). Memory grants: remove granted_memory_mb > 0 filter in both
Dashboard and Lite that hid data when no active grants existed.

Query Trace Patterns: wire up Get Actual Plan for LongRunningQueryPatternItem
using full SampleQueryText (removed artificial 500-char truncation).
View Estimated Plan shows helpful redirect message.

Includes upgrade script (03_default_trace_schema.sql) for 1.3.0-to-2.0.0.
