Wire the frozen #253 ETag/If-Match/412 recipe onto ProgramSchedule / schedule-items, keeping the PR#258 positional in-place reconcile intact. Backend: - ReplaceProgramScheduleItems command gains Option<int> ExpectedVersion; ReplaceScheduleItemsRequest.ToCommand threads it. - Handler: standalone CheckVersion Either AFTER validation (so 412 isn't flattened to 422), unconditional Version++ before save, guarded save via SaveChangesWithConcurrencyGuard, and 412 propagated without running the post-save reload/enqueue. - ProgramScheduleViewModel + Mapper carry Version. - ScheduleController: GET /items emits ETag; PUT /items parses If-Match (malformed -> 400), threads ExpectedVersion, re-queries for the new ETag, and advertises 400/412. - Sibling config-writers (Add/Delete item, Update schedule) bump Version. Frontend: - schedules.ts: getScheduleItemsWithMeta + replaceScheduleItems(ifMatch) returning ResponseWithMeta. - SchedulesScreen: etagRef threaded through the #242 dirty-guard (set from load + every successful save); 412 opens a conflict ConfirmDialog whose Reload discards the draft and re-runs loadItems. Tests: handler concurrency suite (stale->412 no mutation + fill-group state untouched, match/absent success+bump, no-op still bumps, racing save->412); controller ETag/If-Match/412 cases; SchedulesScreen 412-conflict-dialog test.
