fix(deploy): .env.docker resilient — no rm -f, sanity-check vars critiques

- Supprime rm -f (causait la perte de ~23 vars a chaque deploy)
- upsert ecrit KEY=value sans quotes (compatible Docker Compose v2)
- CRLF strip avant ecriture (sed s/\r$//)
- Sanity-check post-upsert: abort si NEXTAUTH_SECRET/AUTH_GOOGLE_ID/etc manquantes
- Header ## AUTO-MANAGED BY CI ## en tete de fichier genere
- deploy-prod.sh: sanity-check pre-deploy (NEXTAUTH_URL/SECRET/GOOGLE_ID/SECRET)
- Ajoute .env.docker.example (reference complete de toutes les vars)
- Ajoute MCP_SERVER_MODE/MCP_SERVER_URL manquantes dans deploy.yaml
