Rule Insights Dashboard for repositories and organizations [GA]

### Value Prop
The Rule Insights Dashboard is now generally available, giving enterprise governance and compliance teams a single place to monitor rule evaluation and adherence across every repository in their organization. You can filter by custom properties, view aggregated metrics, export data to CSV, and access everything programmatically through the REST API — no more stitching together reports repository by repository. Whether you're auditing a single repo or reporting across thousands, you get consistent, reliable visibility in one experience.

### Expected Outcome
Enterprise teams can now track and report on rule adherence at organization scale with confidence, replacing manual, fragmented workflows with a unified dashboard purpose-built for governance. Bringing the repository dashboard to general availability and adding the new org-wide view means compliance teams spend less time aggregating data and more time acting on it. The result is faster, more accurate reporting that scales with the size and complexity of your organization.

The issue describes a generally available Rule Insights Dashboard with organization-wide views, custom-property filters, CSV export, and REST API access, but names no repository files, tests, or implementation entry points. Start by locating the dashboard and API projects; the work is done when repository and organization rule-adherence reporting supports the listed capabilities at scale.
