test(adminui): migrate AdminUI.Tests to v3 greenfield schema + Batch-1 stubs

Migrate tests/Server/ZB.MOM.WW.OtOpcUa.AdminUI.Tests (was 358 build errors) to
the v3 Raw-only Tag schema and the Batch-1 AdminUI stubs. Production untouched.

- Driver-page serialization tests: drop the retired pre-declared Tags editor
  (page *TagRow types + DriverOptions.Tags); multi-device pages keep their
  Devices editor (ToOptions(devices)). Enum-serialization round-trip coverage
  (CpuType/ModbusFamily/MelsecFamily/AbCipPlcFamily/AbLegacyPlcFamily/FocasCncSeries)
  preserved intact.
- UnsTreeTestDb: reseed to v3 (Device->Tag raw slice, no EquipmentId/DriverInstanceId
  on Tag, no Namespace).
- UnsTreeService tag tests: assert Batch-1 stubs (CreateTag/UpdateTag refusal,
  empty tag/tag-driver lists); DeleteTag stays live against a raw Tag.
- Equipment #122 guard retained (validates input driver vs line cluster); drop the
  retired persisted-binding assertions + NamespaceId seeds. Area/Line #122 driver-
  orphan guard retired -> assert cross-cluster move now succeeds.
- DeleteCluster: drop the deleted-Namespace child-check test.
- OpcUaClientTagConfigModel/TagConfigValidator: address key FullName -> nodeId.
- ScriptTagCatalog: project surviving Name/DataType/TagConfig; DriverInstanceId null.
- VirtualTag {{equip}} equipment-tag-derived base is dark -> 3 tests skipped (Batch-3).

Result: build green; 507 passed / 3 skipped / 0 failed.
