Subject: [PATCH] feat(task-management): implement task movement between groups

- Added `moveTaskBetweenGroups` action to facilitate moving tasks across different groups while maintaining state integrity.
- Enhanced task management slice to support task updates during group transitions, including logging for better debugging.
- Updated socket handlers to utilize the new action for moving tasks based on status, priority, and phase changes, improving task organization and user experience.
