feat(task-status-dropdown): enhance task status update and group movement handling

- Added logic to optimistically update task status in Redux for immediate feedback.
- Implemented group movement handling when tasks are updated based on their status, ensuring tasks are moved between groups as needed.
- Improved socket event emissions for real-time updates, including parent task handling.
- Refactored group selection logic to streamline target group identification based on status ID and group value.
