feat(task-management): enhance task management UI with subtask functionality

- Updated task list components to support subtasks, including TaskRowWithSubtasks for rendering tasks with their subtasks.
- Introduced AddSubtaskRow for adding new subtasks directly within the task list.
- Enhanced TaskRow to handle task expansion and display subtask counts.
- Implemented optimistic updates for subtask creation to improve user experience.
- Added loading states for subtasks to provide visual feedback during data fetching.
- Refactored task management slice to manage subtasks and their loading states effectively.
