feat(EnhancedKanbanBoard): add task dependency check during drag-and-drop

- Implemented a check for task dependencies when moving tasks between groups in the EnhancedKanbanBoard component.
- Integrated alert notifications to inform users if a task cannot be moved due to incomplete dependencies, enhancing user experience and task management integrity.
