The legacy create paths (WorkOrderDTOs, SyncService, the Blazor
WorkorderService) still write Status without LifecycleStatus. The board
status filter only matched LifecycleStatus. So an open unassigned row of
that kind was left out of the Unassigned tile and its drill-down list,
even though the Open tile in the same response counted it.
ApplyStatusFilter now reads a row with no LifecycleStatus by its legacy
status (LegacyStatus ?? Status), using the Phase0 backfill rules: known
text maps as LifecycleStatusMapper does, and anything else, blank
included, counts as Incomplete. The tile and /board/search share the
predicate, so the count still matches the list it opens.
