v3 B1-WP6: migrate Core + Server test projects to greenfield schema

Fix TESTS only (production already green) so the four in-scope test projects
compile + pass under the v3 dark address space:

- Core.Abstractions.Tests: drop AllowedNamespaceKinds/NamespaceKindCompatibility
  from DriverTypeMetadata; rewrite EquipmentTagRefResolver tests to the single-func
  RawPath-lookup contract (no parseRef/transient cache).
- Core.Tests: rewrite EquipmentNodeWalkerTests to EquipmentNamespaceContent(Areas,
  Lines,Equipment,VirtualTags?,ScriptedAlarms?) — folders + VirtualTags +
  ScriptedAlarms only; raw-tag variables dark (skipped Batch-4 placeholder). Drop
  retired Equipment.DriverInstanceId.
- Runtime.Tests: rewrite golden corpus + TagConfigCorpusParityTests to the v3
  RawPath/RawTagEntry round-trip (byte + TagConfigIntent parity; EquipmentTags dark).
  Salvage VirtualTag + ScriptedAlarm artifact parity to the new Compose signature.
  Retire the equipment-tag-materialization parity files (Array/Historize/Alias) and
  the equipment-device-binding DeviceHost parity to documented skipped placeholders.
  Skip 34 dark equipment-tag routing/value/alarm/write/discovery actor tests with a
  shared DarkAddressSpaceReasons constant. Re-key cluster-scoped tests to v3 UNS
  line->area attribution.
- ControlPlane.Tests: ConfigComposer round-trips re-keyed to RawFolder/Device (no
  Namespaces); tag-config gate resolves driver via Device; deploy-gate collision test
  re-keyed to UnsEffectiveNameCollision; drop retired BadCrossClusterNamespaceBinding
  case.
