Both inline fields were bare TextInputs: no clear cross, no Escape.
They are QbzSearchField now — Escape empties the filter, hands the
keyboard back and folds the field into its title; the cross empties it
and keeps the caret. The control grew what a 22px header row needs: an
optional leading glyph (the toggle already shows one), a cross sized to
the field, and an `escaped` signal for hosts that fold the field away.
