implement Hilt, DataStore, and Jellyfin SDK

- Setup Hilt for dependency injection and KSP for annotation processing.
- Add DataStore for user session management with JSON serialization.
- Integrate Jellyfin SDK and create a basic `JellyfinApiClient`.
- Replace `MainActivity` with `PurefinActivity` featuring a login flow and a placeholder home screen.
- Implement custom UI components: `PurefinComplexTextField`, `PurefinPasswordField`, and `PurefinTextButton`.
- Update version catalog with new dependencies and downgrade SDK versions to 35.
