- Remove ExtraIds property from BaseItemEntity and BaseItem
- Update RefreshExtras to query via OwnerId instead of cached ExtraIds
- Update GetExtras methods to query database via OwnerIds filter
- Add OwnerIds and ExtraTypes filter support to InternalItemsQuery
- Add filter handling in BaseItemRepository for new query options
- Update HasSpecialFeature/HasTrailer filters to use Extras relationship
- Add CleanupOrphanedExtras migration routine
- Add database migration to drop ExtraIds column
