refactor: update tag data structure and improve tag handling

- Changed `TagsResponse` and `UseTagsState` to include `usage` count in the tag data structure for better tracking.
- Simplified tag initialization in `useTags` to directly use `initialData`.
- Enhanced `TagsPageClient` to filter and sort tags based on usage, improving user experience in tag management.
- Removed unused variables and streamlined the search functionality for better performance.
