- Added search state management to ImprovedTaskFilters, allowing users to filter tasks based on search input.
- Integrated search actions for both list and board views, ensuring appropriate task fetching based on the current view.
- Updated task management slice to include a search field, enhancing the overall task filtering capabilities.
