fix: resolve server test failures for Google Meet integration

- Mock get_google_calendar_object in live class tests to prevent real
  Google API calls in CI (no OAuth tokens available)
- Fix on_trash to clear event link before deleting Event to avoid
  LinkExistsError
- Fix test query to avoid PostgreSQL-incompatible integer filter
- Add Google Settings setup to Google Meet Settings integration tests
