feat: implement unified researcher search and enhance dashboard functionality

- Updated the API service to include a new `searchResearcher` function for streamlined researcher data retrieval.
- Modified `LandingPage` to utilize the new search functionality, reducing the number of API calls.
- Refactored `DashboardPage` to handle the new data structure returned from the search, improving loading efficiency and user experience.
- Enhanced `vite.config.js` and `.env.example` for better API integration and development setup.
- Added health checks in `docker-compose.yml` for database and Redis services to ensure service reliability.
