Subject: [PATCH] Refactor Jellyfin plugin: UI integration, backend contract,
 and STRM creation.

- Integrated "Recommend Film", "Add Movie (STRM)", and Rating UI into Jellyfin web interface.
- Implemented full library sync (metadata with poster URLs, user states) with library filtering support.
- Added support for creating films via .strm file generation.
- Updated MovieNightBackendClient to support sync, recommendations, ratings, and viewed status.
- Added proxy endpoints to MovieNightController for frontend-backend communication.
- Ensured compatibility with Jellyfin 10.11.x and .NET 9.0.
