feat(ui): improve session count display and filter logic

- Added `flex-shrink-0` class to session count text in
  `CardSessionsByList` for better layout handling.
- Introduced conditional filter logic in `SessionsBy` to handle
  `FETCH` metric with specific `FETCH_URL` filter.
- Removed unused filter mapping logic for cleaner code.

This improves UI consistency and enhances filter functionality.
