feat: enhance column visibility toggle with task counts

- Added `tasks` prop to `ColumnVisibilityToggle` for displaying task counts per status.
- Updated `KanbanFilters` to calculate and show counts for priorities and tags, improving filter visibility.
- Integrated task counts into UI elements for better user feedback on task distribution across statuses, priorities, and tags.
