An explicit date range let every undated, non-terminal work order through,
so Unassigned plus a range still returned all ~1,780 unassigned rows. The
range now matches Schedule On, or the Target Week for week-only rows
(overlap), the same date the weekly board groups by. Undated rows are added
only when the caller sends includeDateless, which the client uses for
searches with no range selected and for the Unassigned queue.
