Conflict in ClearanceDocumentsPage: this branch migrated the page to the
pill FilterBar, dev added filters to the Select stack it replaced. Kept
the FilterBar and carried dev's additions across as a "Booked by"
(customerKind) FilterDef plus the shipping-line search placeholder; dev's
startOfDayIso/endOfDayIso went away because dateRangeParams already does
that. The Ship icon import is needed by dev's shipping-line customer cell,
which merged cleanly on its own.
