fix: sync database queries with enhanced media-items schema

- Add missing enhanced fields to CreateMediaItem INSERT statement
- Add missing enhanced fields to UpdateMediaItem UPDATE statement
- Include language, edition, page_count, genre, copyright_year
- Include integration fields: goodreads_id, openlibrary_id, google_books_id
- Add corresponding indexes for enhanced fields
- Add column comments for better documentation
- Resolves schema-query mismatch causing field removal cycles
