v3(b1-wp4b): make AdminUI compile against greenfield schema behind Batch-2/3 stubs

Namespace entity + NamespaceKind retired; DriverInstance dropped NamespaceId;
Tag is raw-only (no EquipmentId/DriverInstanceId/FullName/FolderPath); driver
options replaced pre-declared Tags with RawTags. Stub the retired surfaces so
the AdminUI + Host build green; real Raw/UNS authoring arrives in v3 Batch 2/3.

- ClusterNamespaces/NamespaceEdit: bodies replaced with 'Namespaces retired' banner
- DriverIdentitySection: dropped Namespace dropdown + NamespaceId model field
- 8 driver pages: dropped Namespace binding; retired the pre-declared Tags editor
  (replaced with a '/raw Batch 2' note); multi-device pages keep their Devices editor
- UnsTreeService: equipment-tag counts/list -> empty; Create/UpdateTag -> failure
  result ('Tag authoring moved to the Raw tree (/raw) in v3 Batch 2'); Namespace/
  driver-binding queries removed
- IScriptTagCatalog: project surviving Tag columns only (path from TagConfig FullName, else Name)
- OpcUaClientTagConfigEditor: rebind stale FullName -> model's NodeId
- ClusterDrivers: drop retired NamespaceId column

AdminUI + Host build 0/0. AdminUI.Tests / Host.IntegrationTests remain red (WP6).
