refactor(task-filters): update priority handling in task filters

- Replaced the use of selectedPriorities from taskManagement slice with priorities from taskReducer for consistency across the application.
- Updated dispatch calls in ImprovedTaskFilters to utilize the new setPriorities action, enhancing clarity and maintainability.
- Removed unnecessary imports and streamlined the selector logic for improved performance and readability.
