Rewrite UI API clients from /api/v2/releases to /api/v1/release-orchestrator

Completes Sprint 323 TASK-001 using Option C (direct URL rewrite):
- release-management.client.ts: readBaseUrl and legacyBaseUrl now use
  /api/v1/release-orchestrator/releases, eliminating the v2 proxy dependency
- All 15+ component files updated: activity, approvals, runs, versions,
  bundle-organizer, sidebar queries, topology pages
- Spec files updated to match new URL patterns
- Added /releases/activity and /releases/versions backend route aliases
  in ReleaseEndpoints.cs with ListActivity and ListVersions handlers
- Fixed orphaned audit-log-dashboard.component import → audit-log-table
- Both Angular build and JobEngine build pass clean

 ## Decisions & Risks
 - TASK-001 was resolved by validating existing proxy rewrites rather than introducing more Console changes late in the sprint.
