Subject: [PATCH] fix: preload hi-res NP cover on track change so overlay opens
 instantly

_crossfadeNpBg only preloaded the 1024px cover when the NP overlay was
already open. Opening it fresh showed the old cover for ~0.5s while the
new image downloaded. Preloading in updatePlayerUI caches it immediately.
