feat: implement multi-provider support in media library

- Introduced IProviderRegistry to manage multiple media providers.
- Updated AppState to use provider_registry instead of a single media_provider.
- Refactored library routes to support provider-specific queries for collections, series, genres, and items.
- Enhanced ProgrammingBlock to include provider_id for algorithmic and manual content types.
- Modified frontend components to allow selection of providers and updated API calls to include provider parameters.
- Adjusted hooks and types to accommodate provider-specific functionality.
