- Migrated existing player settings from user_preferences to player_configs.
- Removed player-related columns from user_preferences.
- Added referral state fields to user for tracking referral rewards.
- Created migration scripts for database changes and data migration.
- Added test cases for app services and usage helpers.
- Introduced video job service interfaces and implementations.
