fix(player): stale cover blob and load state on track change (#695)

* fix(player): align cached cover URL with cacheKey on track change

Prevents a one-frame stale blob src (and broken image in the player bar)
when switching tracks; reset CachedImage load state in useLayoutEffect.

* docs: changelog + credits for cover-art track-switch fix (PR #695)
