fix: processing page auto-redirect after file upload completes

Three fixes for the processing page not redirecting when status becomes "ended":

- Add useWebSockets to processing page so it receives STATUS events
- Remove OAuth2PasswordBearer from auth_none — broke WebSocket endpoints (500)
- Reconnect stale Redis in ws_manager when Celery worker reuses dead event loop
