Optimize falukantService and DirectorInfo component for improved performance and user experience

- Refactored proposal handling in falukantService to load existing proposals before cleaning expired ones, reducing unnecessary database queries.
- Enhanced fetchProposals method with explicit joins for better performance and added a limit to avoid excessive data retrieval.
- Updated DirectorInfo component to reload data after hiring a director, ensuring the UI reflects the latest information.
