WebUI: fix size-unit change not persisting when size fields are 0

The min/max size unit dropdowns were wired to a short-circuiting
handler that skipped saving whenever both size inputs were 0,
causing the unit to silently revert on tab switch or reload when
"Remember filters" was enabled. Wire them to searchSizeFilterChanged
directly, matching the Qt widget's behavior.
