Migrate theme asset loads to scheme-variant resolution (#7209-2) (#7276)

Replace remaining QPixmap("theme:...") call sites with themePixmap() so icons, replay controls, card backs, and other images resolve to -dark/-light variants under theme schemes. Stem-exact 1:1 migration; behavior unchanged for non-variant themes.
