feat(configdb): V2HostingAlignment migration consolidating Phase 1a-1e

Phase 1f — the consolidator migration. Closes out the v2 entity-model
rewrite by emitting a single EF migration that captures the cumulative
schema delta from 14a (RowVersion) through 14e (drop generation entities).

Generated: src/Core/ZB.MOM.WW.OtOpcUa.Configuration/Migrations/
              20260526081556_V2HostingAlignment.cs           (1562 lines)
              20260526081556_V2HostingAlignment.Designer.cs

Migration shape (per `grep -nE migrationBuilder.\(...)`):

  Drop  12 ForeignKey constraints (one per live-edit entity's GenerationId FK)
  Drop  2  Tables  (ConfigGeneration, ClusterNodeGenerationState)
  Drop  45 Indexes (every UX_*_Generation_* and IX_*_Generation_* across the
                    13 live-edit tables — 1 also dropped the unique-Primary
                    filtered index UX_ClusterNode_Primary_Per_Cluster)
  Drop  13 Columns (12 GenerationId + 1 RedundancyRole)
  Add   12 RowVersion columns (one per live-edit entity)
  Create 4  Tables (Deployment, NodeDeploymentState, ConfigEdit,
                    DataProtectionKeys)
  Create ~45 Indexes (recreated under the new naming pattern
                      UX_<Table>_LogicalId / UX_<Table>_<X> with the
                      GenerationId column stripped from composite keys)

Notable EF quirks accepted:
  Unique-on-required-column indexes (UX_VirtualTag_LogicalId etc.) ship a
  `filter: "[VirtualTagId] IS NOT NULL"` clause that EF auto-inserts for
  SQL Server. Harmless — the column is C#-side `required` so NULL never
  appears.

Live `dotnet ef database update` against a scratch SQL Server deferred to
Task 15 (Migrate-To-V2.ps1) — SSH to the docker host needs a key/password I
don't have, and the always-on SQL at 10.100.0.35,14330 uses Integrated
Security (Windows auth, unreachable from this macOS dev). The migration
itself is structurally correct by construction (EF tooling generated it
against the live DbContext model); the live-DB confidence step is the
PowerShell wrapper's job.

SchemaComplianceTests updates:
  - All_expected_tables_exist: removed ConfigGeneration +
    ClusterNodeGenerationState; added Deployment, NodeDeploymentState,
    ConfigEdit, DataProtectionKeys.
  - Filtered_unique_indexes_match_schema_spec: removed entries for
    UX_ClusterNode_Primary_Per_Cluster (Task 14d) and
    UX_ConfigGeneration_Draft_Per_Cluster (Task 14e). Two filtered uniques
    remain (UX_ClusterNodeCredential_Value, UX_ExternalIdReservation_KindValue_Active).
  - Check_constraints_match_schema_spec: added CK_ConfigEdit_FieldsJson_IsJson.

StoredProceduresTests update:
  - Removed RedundancyRole + 'Primary' from the raw INSERT into ClusterNode
    so the DB-backed test runs against the new schema.
