Add Helm support for Grafana dashboard annotations (including folder assignment)

[Copilot]

Users enabling chart-managed Grafana dashboards could not attach annotations to the generated dashboard resources, which blocked common workflows like folder assignment via grafana_folder. This change adds first-class annotations support for dashboard manifests.

• Helm values surface

  • Added dashboards.annotations to chart values to allow arbitrary metadata annotations on dashboard resources.

• Dashboard template rendering

  • Updated templates/dashboards.yaml to render metadata.annotations from dashboards.annotations on:
    • the dashboards ConfigMap
    • both GrafanaDashboard resources (general and internal) when CRDs are available.
  • Normalized metadata label indentation in GrafanaDashboard blocks while touching this area.

• Chart tests and docs

  • Extended tests/dashboards_test.yaml to assert annotation rendering on both ConfigMap and GrafanaDashboard manifests.
  • Updated chart README values table to document dashboards.annotations.

Example values:

dashboards:
  enabled: true
  annotations:
    grafana_folder: my-folder

Pull request overview

Adds first-class Helm values and template support to attach arbitrary metadata.annotations onto the chart-managed Grafana dashboard resources, enabling workflows like Grafana Operator folder assignment via grafana_folder.

Changes:

• Added dashboards.annotations to chart values (and documented it) to allow user-supplied annotations.
• Rendered dashboards.annotations onto the dashboards ConfigMap and both GrafanaDashboard CRs (when the CRD is available), alongside a small label indentation normalization.
• Extended Helm unit tests to assert annotation rendering on both ConfigMap and GrafanaDashboard manifests.
