Enhance task status handling and progress visualization in Kanban board

- Introduced a mechanism to emit a socket event when a task's status changes during drag-and-drop operations.
- Updated TaskCard to consistently display the progress circle regardless of task completion state.
- Improved TaskProgressCircle to handle complete_ratio and progress more robustly, ensuring accurate visual representation.
