fix: Gitea CI/CD und Blank-Page-Fehler behoben

- Helmet CSP: upgrade-insecure-requests und HSTS für HTTP-Deployments deaktiviert
  (war die Ursache der leeren Seite - Browser versuchte JS über HTTPS zu laden)
- Backend: statische Dateien werden jetzt in allen NODE_ENV-Modi serviert
- Frontend: IS_DEV erkennt auch VITE_TEST_MODE=true (Build-Zeit Variable)
- Dockerfile: VITE_TEST_MODE=true beim Vite-Build, NODE_ENV=development
- docker-compose.yml: NODE_ENV=development, CORS_ORIGIN=*
- Gitea Workflow: Auth-Token für git clone, Build via Portainer API statt lokaler Docker CLI
