Fix JavaScript URL construction error for API endpoint

- Change NEXT_PUBLIC_ENTE_ENDPOINT from "/api" to "https://example.com/api" during build to satisfy URL constructor requirements
- Add runtime replacement in start.sh to replace placeholder with actual domain endpoint
- This resolves the "TypeError: Failed to construct 'URL': Invalid URL" error in the frontend
