Corregir compose producción y nginx.conf

- nginx.conf: eliminar text/html de gzip_types (duplicado con default de nginx)
- compose: webroot apunta a /var/volumes/web_jailgames directamente
- compose: conf nginx montada como jailgames.conf (no default.conf)
  para evitar que el entrypoint la sobreescriba al arrancar
- healthcheck: usar pgrep nginx en lugar de wget (más fiable)
