feat: optimize label pagination and read progress handling

- Optimize calculatePages() to show single page when ≤12 labels
- Add loading animation for initial label loading only
- Unify label filtering logic in ViewModel instead of UI
- Fix read progress regression by always taking higher value
- Prevent server updates with lower progress values
- Improve UX with better loading states and pagination
