Added missing database tables and columns for video engagement:
- sexy_video_likes: tracks user likes on videos
- sexy_video_plays: tracks video play analytics
- sexy_videos: added likes_count, plays_count, views_count columns
This enables the like/unlike feature and video analytics that were
already implemented in the frontend but missing the database schema.
Tables include proper indexes and foreign key constraints for performance.
