fix: rename metadata to extra_meta to avoid SQLAlchemy reserved field conflict
SQLAlchemy's 'metadata' attribute is reserved for model metadata, causing
service startup crash. Changed to 'extra_meta' with Column('metadata', JSON)
mapping to preserve database column name.
Affected models (7):
- AssetLibraryModel, AssetModel, AssetClassificationModel
- GenerationTaskModel, DuplicationRecordModel
- TitleLibraryModel, VoiceLibraryModel
Updated all references across:
- packages/adapters/sqlalchemy_impl/{title_library,voice_library,asset}_repository.py
- apps/worker/worker_app/{core/asset_usage.py,tasks/voice_extraction.py}
- apps/api/app/api/routes/{asset_diagnosis.py,assets.py}
