fix: update KanbanFilters to use regularTasks instead of tasks

- Changed `tasks` to `regularTasks` in `KanbanFilters` for accurate task counting.
- Updated priority and tag count calculations to reflect the new `regularTasks` prop, ensuring filters work with non-pinned tasks.
- Adjusted `TasksContext` to provide `regularTasks`, enhancing task management clarity.
