With NowPlaying (or an ABS player) open, backgrounding and resuming the app made the next back
press pop the NavHost invisibly to Home before dismissing the overlay. Returning from the
background re-registers the NavController's own OnBackPressedCallback on top of the dispatcher,
stealing back-priority from the overlays.
AppNavigation now bumps a resumeTick on Lifecycle.Event.ON_RESUME and keys every overlay
DisposableEffect (NowPlaying, ABS player, ABS item, Erkunden overlay) on resumeTick +
currentBackEntry, so each overlay re-adds its callback above the NavController after a resume or
navigation. Needs on-device verification.
