fix(settings): make the rescan slider visible on light themes

Browse Source 
The scan-height slider drew its track, % label, and thumb in pure white, which
vanished on light skins because the glass sub-section goes opaque white there
(only the numeric input showed). Switch those to OnSurface-based colors so they
adapt: near-white on dark (unchanged look) and dark on light (now visible).
Surfaced by the full Windows UI sweep on the marble/light skins.
