Infrastructure Grafana dashboards missing in default variant monitoring #2349

Description

PR #2197 scoped infrastructure dashboards to tenant-root namespace only, but the "default" variant deploys monitoring to the cozy-monitoring namespace. As a result, infrastructure dashboards (VictoriaMetrics, Flux, Hubble, LINSTOR, control-plane, etc.) are no longer rendered in the default variant.

Root cause

In packages/system/monitoring/templates/dashboards.yaml, the infra dashboards are conditionally rendered only when Release.Namespace == "tenant-root":

{{- if eq .Release.Namespace "tenant-root" }}
  {{- range (split "\n" (.Files.Get "dashboards-infra.list")) }}
  ...
  {{- end }}
{{- end }}

However, the default variant installs monitoring in the cozy-monitoring namespace (defined in packages/core/platform/sources/monitoring.yaml):

install:
  privileged: true
  namespace: cozy-monitoring

Since cozy-monitoring != tenant-root, the condition is false and all infra dashboards from dashboards-infra.list are skipped.

Expected behavior

Infrastructure dashboards should be available in the platform-level monitoring deployment regardless of variant. The condition should account for both tenant-root and cozy-monitoring namespaces (or more generally, distinguish platform-level monitoring from per-tenant monitoring).

Affected dashboards (dashboards-infra.list)

VictoriaMetrics, Flux, Hubble, LINSTOR, control-plane, main dashboard, and other infrastructure-level dashboards.

Affected files

• packages/system/monitoring/templates/dashboards.yaml — namespace condition too restrictive
• packages/system/monitoring/dashboards-infra.list — infra dashboard list
• packages/core/platform/sources/monitoring.yaml — defines cozy-monitoring namespace for default variant
