feat: add search functionality to configuration table

- Added search input box that filters by configuration name and description
- Real-time filtering as user types with case-insensitive matching
- Clear search button (✕) appears when search term is entered
- Improved layout with flexbox for search and category controls
- Enhanced results messaging: shows "Found X matching settings" when searching
- Better empty state messaging with option to clear search
- Responsive design with flex-wrap for mobile compatibility
