Summary

Delete the old 3-phase Helm chart upgrade plan (predates Mikado system)
Create C2 Mikado chain with goal card upgrade-grafana and two leaf prereqs:
- kustomize-grafana-deployment — convert Helm to kustomize manifests
- build-grafana-container — home-built Grafana 12.x image (no upstream containers)
Record first-ever Grafana review: currently at v11.4.0 on Helm chart 8.8.2
Update service-versions.yaml, how-to index, and plans index

Service Review Findings

Grafana is healthy and synced in ArgoCD
Running v11.4.0, latest upstream is 12.3.3
Breaking changes for 12.x are low-risk (React panels only, UIDs compliant)
PVC is disposable — dashboards and datasources are all config-provisioned

Deployment and Testing

No deployment needed — documentation-only change
docs-check-links passes
docs-check-index passes

Review Grafana: replace Helm upgrade plan with C2 Mikado chain 0e97661879

The old 3-phase Helm chart upgrade plan predates the Mikado system.
Replace it with a proper C2 chain that targets Grafana 12.x with
kustomize manifests and home-built containers (no upstream images).

Cards:
- upgrade-grafana (goal, requires both below)
- kustomize-grafana-deployment (leaf)
- build-grafana-container (leaf)

Also records the current deployed version (v11.4.0) in
service-versions.yaml from the first-ever Grafana review.
