Implement episode metadata management: add functionality to refresh episode metadata from external sources, including new API endpoints and UI integration. Enhance Show and Episode models to support additional metadata fields, and update database schema accordingly. Update ShowDetail and ShowMetadataCard components to display refreshed episode information and provide user feedback on metadata updates.
