feat: activate BunkerM MQTT broker + fix Telegraf

- BunkerM: recreated with port 1883 (external) -> 1900 (internal)
- BunkerM: disabled dynsec plugin, using password_file auth (bunker/bunker)
- Simulator: ENABLE_BUNKER=1, BUNKERM_PORT=1900
- Telegraf: reactivated BunkerM consumer on port 1900
- Telegraf: recreated container (3 MQTT consumers connected)
- Grafana: dashboard v4 with corrected Flux queries
- Grafana: datasource fixed (bucket=smartcity, token=my-super-token)

Verified:
- Simulator publishes to EMQX ✅, Mosquitto ✅, BunkerM ✅
- Telegraf receives from all 3 brokers ✅
- InfluxDB has data from all brokers ✅
- Grafana dashboard displays data ✅

+- **Grafana** : Dashboard smartcity-martinique-complete v4 — données confirmées ✅

 - **InfluxDB** : bucket `smartcity`, measurement `mqtt_consumer`, tag `topic` pour le type
 - **OpenRemote** : Abandon pour l'instant, l'utilisateur va recloner le répertoire
 - **Keycloak** : Recréé manuellement (ancien supprimé par docker-compose up échoué)
+- **Grafana provisioning** : smart-city-dashboards.json déplacé en .bak pour éviter écrasement
