feat(task-management): implement task reordering and group updates via API

- Added API methods for reordering tasks and updating task groups (status, priority, phase).
- Enhanced task management slice with async thunks for handling task reordering and group movements.
- Updated task list board to support real-time updates during drag-and-drop operations, emitting socket events for task sort order changes.
- Refactored task-related components to utilize shared Ant Design imports for consistency and maintainability.
- Removed unused Ant Design imports and optimized drag-and-drop CSS for improved performance.
