refactor(task-list): update status handling and enhance styling in TaskListV2Table

- Modified status assignment in useTaskSocketHandlers to utilize actual status_id from the response for improved accuracy.
- Simplified status logic by directly using data.status in task creation.
- Enhanced styling in TaskListV2Table by adding border styles for better visual separation of elements.
