Subject: [PATCH] add complete data persistence for Grafana and Prometheus
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add persistent volumes for grafana_data and prometheus_data
- Create Grafana provisioning configuration for automatic Prometheus datasource
- Add dashboard provisioning setup with proper directory structure
- Eliminate need to manually configure Grafana-Prometheus connection
- Data now persists across container restarts (API keys, metrics, dashboards)
- Grafana automatically connects to Prometheus on startup

Key files:
- grafana/provisioning/datasources/prometheus.yml: Auto-configures Prometheus datasource
- grafana/provisioning/dashboards/dashboard.yml: Dashboard provisioning config
- Updated docker-compose.yml with persistent volumes and volume mounts
