Apache ProxyPass targets host port 8069; update compose, CI, CORS defaults, deployment docs, and production .env files for https://sinbad2.ujaen.es/generadorexamenesllm/.
Configure GitLab deploy pipeline for this app and switch backend/frontend endpoint defaults from localhost to sinbad2.ujaen.es, including Docker, env files, API client, CORS, and docs.
Track backend .env in the private production repository so deployment keeps the required runtime settings.
