fix: pipeline CI/CD — vps-runner direct deploy (pm2 + rsync)

Remplace le flow Docker (docker compose up) par le vrai modèle :
- Job unique sur vps-runner (runner local sur le VPS)
- Build backend → rsync vers /var/www/originsdigital/backend/ → pm2 restart
- Build frontend avec VITE_API_URL/VITE_SUPEROAUTH_URL → rsync vers /var/www/originsdigital/frontend/dist/
- Suppression appleboy/ssh-action (inutile, le runner est sur le VPS)
