Implement bulk tagging and enriching of shows with new API endpoints and frontend integration

Added new API endpoints for bulk tagging and enriching shows, allowing for mass updates of genres and audience ratings. Implemented backend logic to handle bulk operations and updated the Dependency Injection configuration to include necessary services. Enhanced the frontend with new components for selecting shows and applying bulk actions, improving the user experience for managing multiple shows simultaneously. Localization updates were made to support these new features in both English and Russian.
