Implement task completion prompt and enhance progress handling

- Added logic to prompt users to mark tasks as done when progress reaches 100%, integrating with the socket events for real-time updates.
- Updated backend functions to check task statuses and determine if a prompt is necessary based on the task's current state.
- Enhanced frontend components to display a modal for confirming task completion, improving user experience and clarity in task management.
- Refactored socket event handling to include new events for retrieving "done" statuses, ensuring accurate task status updates across the application.
