fix: blocklist-search queue ID type mismatch and bump version to 1.7.16

- Cast arrQueueId to String in both sides of the download lookup comparison
  in /api/dashboard/blocklist-search to resolve false-negative match failure
  caused by DOM dataset string vs Radarr/Sonarr API number type mismatch
- Add regression integration test for string-vs-number arrQueueId matching
- Bump version to 1.7.16, update CHANGELOG.md, openapi.yaml, and JSDoc examples

Resolves #48
