…tness tests

- Add optional `type: String?` parameter to `getWorkflows` path, operation,
  API method, and mock, matching Android PR #3509 which supports
  `?type=<value>` query filtering on the list endpoint
- Include `type` in the operation deduplication cache key so calls with
  different types are not coalesced
- Add `testGetWorkflowsWithTypePassesQueryParameter` with snapshots for all
  OS variants
- Add `WorkflowSummaryDecodingTests` covering explicit-null `offering_id`,
  absent `prefetch` default, and unknown-field tolerance for both
  `WorkflowSummary` and `WorkflowsListResponse`
- Remove unnecessary `import Foundation` from `WorkflowsListCallback.swift`

…ache key separator and indentation

- Move .getWorkflows to supportsSignatureVerification=true, matching .getWorkflow and Android PR (#3509)
- Add "\n" separator between appUserID and type in individualizedCacheKeyPart to prevent collision
- Fix indentation of factory closure closing brace and label to match GetWorkflowOperation pattern

* feat(networking): add getWorkflows list endpoint

Port of RevenueCat/purchases-android#3509

Adds WorkflowSummary and WorkflowsListResponse models, GetWorkflowsListOperation,
and WorkflowsAPI.getWorkflows() to support listing a subscriber's workflows via
GET /v1/subscribers/{userId}/workflows. Includes request deduplication and
background-aware delay, matching the existing getWorkflow(by id) pattern.

* Add WorkflowsListCallback and GetWorkflowsListOperation to Xcode project

Register the two new source files in the root RevenueCat.xcodeproj so
xcodebuild (used by CI) can find them. SPM discovers them automatically
but the tracked root project needs explicit file references and build
file entries.

* Fix snapshots: remove ?type=paywall query param from getWorkflows endpoint

The getWorkflows endpoint does not send a type filter query parameter.
The snapshots were created from an earlier design and needed to be
updated to match the actual request URL.

* Fix WorkflowSummary decoding with JSONDecoder.default convertFromSnakeCase

JSONDecoder.default uses .convertFromSnakeCase, which converts JSON keys to
camelCase before matching against CodingKey raw values. The explicit CodingKeys
had snake_case raw values (e.g. "display_name"), causing a mismatch since the
decoder would convert display_name to displayName before the lookup.

Removing the explicit CodingKeys lets Swift synthesize them with camelCase raw
values, which correctly match the converted keys.

  `?type=<value>` query filtering on the list endpoint
- Include `type` in the operation deduplication cache key so calls with

* Address review: enable signature verification for getWorkflows, fix cache key separator and indentation

- Move .getWorkflows to supportsSignatureVerification=true, matching .getWorkflow and Android PR (#3509)
- Add "\n" separator between appUserID and type in individualizedCacheKeyPart to prevent collision
- Fix indentation of factory closure closing brace and label to match GetWorkflowOperation pattern
