Register AlbumArtService with service locator and update gitignore

This commit completes the AlbumArt feature integration by registering
the service with the dependency injection system and updating repository
ignore rules.

Service Registration:
- Initialize AlbumArtRepository with EntityManagerFactory
- Create AlbumArtService instance with repository dependency
- Register AlbumArtService with ServiceLocator for handler injection
- Ensures all AlbumArt action handlers can resolve dependencies

The service follows the established initialization pattern used by other
entities (SamplingRate, BitDepth, BitRate, etc.) ensuring consistency
across the application architecture.

Repository Configuration:
- Add src/scripts/* to .gitignore for local script files
- Add local-repo/ to .gitignore for local Maven repository cache
- Prevents accidental commits of development artifacts and dependencies

These changes complete the AlbumArt feature, making it fully operational
and accessible through the action handler system.
