feat(task-management): enhance priority and status dropdowns with fallback rendering

- Added helper functions to display names and colors for raw priority and status values, improving user experience.
- Implemented fallback rendering for dropdowns to handle cases where the priority or status is not found in the list.
- Updated task row to display formatted priority and status values, ensuring consistency across the UI.
- Enhanced error handling in task list rendering to provide meaningful feedback when data is unavailable.
