Add drill-down namespace views under the Polaris sidebar entry. Each namespace gets a sidebar sub-item registered dynamically from audit data, linking to /polaris/:namespace with a score summary and per-resource table. Introduces a shared PolarisDataContext so the sidebar registrar and view components share a single data fetch. Also updates the Artifact Hub repository ID.
