feat: implement core search and content management functionality

- Add semantic search API endpoint with mock data and debounced search
- Create useSearch hook for managing search state and API calls
- Implement SearchResults component with rich item display
- Add ImageDropzone component with drag-and-drop file upload support
- Create upload API endpoint for file and URL processing
- Build ItemDetailsModal with comprehensive metadata display and actions
- Add Badge UI component to design system
- Integrate search functionality into main interface with real-time results
- Support multiple image formats with validation and size limits
- Add item management actions (share, download, copy, favorite, edit, delete)

Core features now working:
✅ Real-time semantic search with debouncing
✅ Image upload via drag-and-drop or URL
✅ Detailed item view with metadata and actions
✅ Responsive UI with proper loading states and error handling
