fix: approval legacy route prefix and jobengine orchestrator alias

- Fix approval.client.ts legacy URL from /api/release-orchestrator/ to
  /api/v1/release-orchestrator/ matching gateway route config
- Add orchestrator.stella-ops.local alias to jobengine container so
  gateway route translation resolves correctly
- Update sprint execution log with QA iteration results (40/40 pages clean)
