fix: restore timeout and fix celery test infrastructure

- Re-add timeout=1.0 to ws_manager pubsub loop (prevents CPU spin)
- Use Redis for Celery tests (memory:// broker doesn't support chords)
- Add timeout param to in-memory subscriber mock
- Remove duplicate celery_includes fixture from rtc_ws tests
