feat(mobile): Add tags screen to mobile app (#2163)

* feat: Add tags screen to mobile app

Add a new Tags tab to the mobile app that displays all tags sorted by usage.
The screen includes:
- Paginated tag list with infinite scroll
- Display of tag names and bookmark counts
- Pull-to-refresh functionality
- Navigation to individual tag detail screens
- Empty state and loading indicators

This brings tag browsing functionality to the mobile app, similar to the
existing Lists tab.

* feat: Add search functionality to mobile tags screen

Add a search input to the tags screen that allows users to filter tags
by name. The search includes:
- Debounced search input (300ms delay) to reduce API calls
- Real-time filtering as the user types
- Sort by relevance when searching, by usage when not searching
- Smooth animated clear button

This enhances the tags browsing experience by making it easy to find
specific tags in a large collection.
