Subject: [PATCH] fix(monitoring): Migrate Grafana Helm chart to
 grafana-community repo

The grafana chart in grafana.github.io/helm-charts is now deprecated
(frozen at chart 10.5.15 / Grafana 12.3.1, marked deprecated: true) after
Grafana Labs forked the charts to grafana-community/helm-charts on
March 16, 2026. Installs emit "WARNING: This chart is deprecated".

Point the grafana chart at the maintained community repo
(grafana-community/grafana, chart 12.7.2 / Grafana 13.1.0) in both
monitoring.sh and perf-platform.sh. All values keys used by the scripts
(admin, service, persistence, resources, sidecar, plugins, grafana.ini)
remain valid in the new chart.

The pyroscope chart was not moved, so perf-platform.sh keeps the original
grafana repo alongside the new grafana-community repo for grafana/pyroscope.
