Subject: [PATCH] Update Nginx configuration and mock mode initialization for
 improved backend handling

- Modified Nginx configuration to trust the outer reverse proxy's X-Forwarded-Proto header, enhancing protocol handling.
- Updated initMockMode function in mock.ts to use the backend health endpoint for improved error handling and timeout management, ensuring a more robust fallback to mock data when the backend is unreachable.
