feat: implement TMDb enrichment for movie profiles

- Add SqliteMovieProfileRepository for managing movie profiles in SQLite.
- Create TmdbEnrichmentClient to fetch movie details from TMDb API.
- Implement enrichment event handling with EnrichmentHandler.
- Introduce periodic jobs for cleaning up expired import sessions and checking for stale movie profiles.
- Update application context to include movie profile repository.
- Add API endpoint to retrieve movie profiles.
- Extend domain models with new structures for movie enrichment (Genre, Keyword, CastMember, CrewMember, MovieProfile).
- Modify event system to include MovieEnrichmentRequested event.
- Enhance tests to cover new functionality and ensure stability.
