Acceptance Criteria

Each entity should have:

• definition.yml updated with goldenTags (gcp.projectId, gcp.region) and ownership
• golden_metrics.yml migrated to FROM Metric with gcp query type
• summary_metrics.yml with providerAccountName and gcpProjectId tags
• dashboard.json using dimensional metric queries
