feat: Add Grafana dashboard as ConfigMap

Adds the Grafana dashboard for iperf3-monitor as a ConfigMap to the Helm chart.

The dashboard is sourced from the project's README and stored in
`charts/iperf3-monitor/grafana/iperf3-dashboard.json`.

A new template `charts/iperf3-monitor/templates/grafana-dashboard-configmap.yaml`
creates the ConfigMap, loading the dashboard JSON and labeling it with
`grafana_dashboard: "1"` to enable auto-discovery by Grafana.
