feat(backend): add genres support to AniList integration

Add the `genres` field to AniList GraphQL queries and type definitions:
- Add genres field to GetAniListItem query for fetching single anime details
- Add genres field to AniListSearch query for search results
- Add genres field to GetAniListUserWatchingList query for user's watch list
- Update MediaList type definition to include Genres []string field

This enhancement allows the application to retrieve and display anime genre
information from the AniList API, providing users with better categorization
and discovery capabilities.
