fix: Simulateur MQTT 3/4 + OpenRemote master + Mapsettings

- MQTT OK: 3/4 (EMQX, Mosquitto, BunkerM)
- OpenRemote: utilise realm master (token fonctionnel)
- Realm smartcity recréé dans Keycloak
- Assets IOTSensor créés dans master (30) et smartcity (30)
- Mapsettings: layers iot-sensors + labels pour master et smartcity
- INTERVAL=5s, réseau openremote_default ajouté
- Dockerfile: --no-cache rebuild
