fix(dialog): keep sortable column headers visible in narrow Save/Open windows

In Mode::Dialog (file picker), the location_view used to drop the sortable
heading row whenever the window dropped below the 600px condensed threshold —
which is most of the time for Save As dialogs (the min window width is 360px).
Users lost the ability to click Name/Modified/Size to toggle ascending /
descending sort.

Add a compact heading row reused in dialog mode when the window is condensed.
It keeps the same Message::ToggleSort(HeadingOptions) wiring; only the
column widths differ (Length::Shrink instead of Fixed) so it fits in a
narrow dialog. The regular wide layout is unchanged.
