Usage:
  ./deploy-production.sh [--with-pgmanage] [--skip-prune]

What it does:
  1. Validates .env.docker.production
  2. Loads IMAGE_TAG, APP_IMAGE, registry, and archive settings from the env file
  3. Loads a matching Docker image archive from IMAGE_ARCHIVE_DIR when present
  4. Otherwise logs in to the registry if credentials are configured, then pulls
  5. Reuses healthy Traefik, Postgres, and Redis containers when present
  6. Waits for health checks and prints container status

VPN/shared-folder image flow:
  Put an archive matching IMAGE_TAG in ./image-archives before running this script.
  Example: ./image-archives/carmanagement-latest.tar
