Merge origin/dev (vendor roadmap PRs #28/#29, phases 1-3 PRs #13-15)
into work-orders-phase-4. Conflict in WorkOrderController.cs resolved by
keeping both the Phase 4 board/search endpoint and the dev-side XML doc
comment on GetDispatcherLookups (both additions at the same site).
Migration timestamps remain monotonic and non-overlapping. Phase 4 global
advanced search, search index migrations, and the cross-platform LocalDB
test guard are preserved alongside the merged vendor roadmap and phases 1-3.
Validation (Docker .NET 8 SDK): build 0 errors; 191 tests pass across
all three test projects (64 + 18 + 109).
Harden contextual search on the weekly board and expose paginated cross-week GET /board/search with date presets, FE filter params, SQL indexes, and unit tests.
Expose POST /api/workorders/board and POST /api/workorders/{id}/cancel for SHOC wizard/inline creation and soft cancel, with field locks, WO# normalization, and Admin-only hard delete.
- GET /api/workorders/board with week window, Unscheduled section, and X of Y counts
- GET /api/workorders/lookups/dispatchers for SHOC filter avatars
- Board projection via WorkOrderBoardDataService with vendor/dispatch join and derived isPastDue
- Phase1_BoardIndexes migration (IX_workOrders_ScheduledDate)
- 5 board unit tests
