feat(compliance): add 'View in Reporting' link for 2.3.x Ivanti metrics

In ComplianceDetailPanel, active metrics with a metric_id starting with
'2.3' and an Ivanti_Vulnerability_ID in extra_json now surface the ID
prominently alongside a 'View in Reporting →' button. Clicking navigates
directly to the Reporting page. onNavigate prop threaded through
App → CompliancePage → ComplianceDetailPanel → MetricRow.
