Add isFollowedByCurrentUser field and hasFollowing to feed query

Updated GraphQL operations to support efficient follow status checking:
- Added isFollowedByCurrentUser field to UserSocialsFields fragment
- Removed nested followers array from UserSocialsFields (over-fetching)
- Simplified followUser/unfollowUser mutations to return minimal data
- Added hasFollowing field to GetVideoFeed query for feed mode detection
- Updated getUserFollowingFollowers query to include isFollowedByCurrentUser

These changes enable the mobile app to:
- Display correct follow/unfollow button states without client-side lookups
- Differentiate between "Following" and "Popular" feed modes
- Reduce payload size by removing unnecessary nested data

Backend handles efficient resolution via request-scoped caching.
