Implement task priority and due date features in task management

- Added `TaskPriority` enum to define task priority levels: none, low, medium, high, and urgent.
- Introduced `dueDate` field in the Task model to allow setting deadlines for tasks.
- Updated task creation and update actions to handle priority and due date inputs.
- Enhanced UI components to display and manage task priority and due date effectively.
- Updated project plan to reflect the addition of task priority and due date functionalities.
