Merge origin/main (West Jeff) into wilm

Bring in the natural-key import fix, Metrics->Monitors rename, PC detail tabbing and panel groups, guest search grants, and the 2026-08-30 security fixes. Reconcile endpoint packaging/installer, migrations, contract version, and tests; keep the delivery uninstaller and 6-step installer alongside main's permission-based RBAC and pin-drift protection.
