feat(adminui): F15 Phase D — logic + ops pages

- ClusterAudit (/clusters/{id}/audit) — reads ConfigAuditLog with the
  EventId/CorrelationId columns added in F3; shown as a Cluster tab
- VirtualTags (/virtual-tags)            — fleet-wide read view
- ScriptedAlarms (/scripted-alarms)      — fleet-wide read view
- Scripts (/scripts)                     — fleet-wide; expandable code preview
- RoleGrants (/role-grants)              — per Q4, surfaces the fleet-wide
                                           LDAP-group → role mapping from
                                           Authentication:Ldap:GroupToRole
                                           (read-only; reload via host restart)
- Certificates (/certificates)           — own/trusted/issuer/rejected store
                                           contents resolved against
                                           OpcUa:PkiStoreRoot config (F13a)
- Reservations (/reservations)           — ExternalIdReservation table
- AlarmsHistorian (/alarms-historian)    — live HistorianAdapterActor sink
                                           status via the F11 GetStatus query;
                                           5s polling

ScriptLog deferred (needs the F16-deferred ScriptLogHub bridge).
ClusterNav extended with the Audit tab.

Adds an AdminUI → Runtime project reference so the historian status page can
inject IRequiredActor<HistorianAdapterActorKey>. NuGet audit suppression for
the transitive Opc.Ua.Core advisory mirrored from the Runtime project.

All 104 v2 tests still green.
