kustomize 5.4.3 (bundled in ArgoCD) removed localChartPath and chartPath
from its JSON schema, making helmCharts: with a local chart path invalid.
Pre-render the base manifests with 'make render-helm' instead; overlays
patch the plain YAML as before. ServiceMonitor excluded until Prometheus
is installed.
