feat(task-list): implement optimized task group handling and filter data loading

- Introduced `useFilterDataLoader` hook to manage asynchronous loading of filter data without blocking the main UI.
- Created `TaskGroupWrapperOptimized` for improved rendering of task groups with drag-and-drop functionality.
- Refactored `ProjectViewTaskList` to utilize the new optimized components and enhance loading state management.
- Added `TaskGroup` component for better organization and interaction with task groups.
- Updated `TaskListFilters` to leverage the new filter data loading mechanism, ensuring a smoother user experience.
