Enhance PLib video library manager with new tabbed navigation for entities and metadata management. Introduce sections for videos, tags, actors, studios, collections, and metadata, each with dedicated search and sorting capabilities. Update UI components to reflect these changes, ensuring a cohesive user experience. Revise repository interfaces to support loading video items with labels and summaries for efficient browsing. Update README.md to document new features and usage instructions.
