refactor: make authentication truly transparent proxy

- Pass through ALL Jellyfin responses (success and error) without modification
- Move session capabilities posting to background task (don't block auth response)
- Remove generic error fallbacks - always return Jellyfin's actual response
- Simplify logic: if Jellyfin returns a response, pass it through; if not, return status code only
