refactor(adminui): B2-WP8 DriverTypeNames rewire + retire routed driver-authoring flow

Part 1 — rewire the three DriverType dispatch maps from hand-authored string
literals to the canonical DriverTypeNames constants (single source of truth):
- TagConfigEditorMap, TagConfigValidator (AdminUI)
- EquipmentTagConfigInspector (ControlPlane)
This FIXES the live drift ("TwinCat"->TwinCAT, "Focas"->FOCAS). The maps are
OrdinalIgnoreCase so behavior is identical; the value is no future drift.
Calculation is not added to the inspector (no CalculationTagDefinitionFactory.Inspect).
Added TagConfigDriverTypeNameGuardTests pinning the maps to the constants.

Part 2 — retire the routed /clusters/{id}/drivers driver-authoring flow (/raw
Waves A-C now cover driver/device/tag authoring end-to-end):
- Deleted DriverTypePicker, DriverEditRouter, the 8 *DriverPage shells, and the
  ClusterDrivers list page.
- Removed the "Drivers" tab from ClusterNav. Routes /clusters/{id}/drivers* now
  simply do not exist -> clean 404.
- The Forms/DeviceForms bodies, shared driver sections, and address pickers used
  by the /raw modals are untouched.

Part 3 — updated PageAuthorizationGuardTests census: removed the 10 deleted
ConfigEditor pages + ClusterDrivers, updated group-count comments (ConfigEditor
21->11, AuthenticatedRead 17->16). Removed the now-dead Clusters.Drivers usings
from the 4 *DriverPageFormSerializationTests + the guard test.
