fix: reconcile native state on app foreground; refresh playlist after delete

- Call reconcileNativeState() on visibilitychange→visible so the player UI
  updates immediately when the user opens the app after a background auto-advance,
  before deferred evaluateJavascript callbacks have had a chance to fire
- After deleteSong() succeeds, refresh the active playlist view (grid or detail)
  with a 2s delay to let Navidrome's background scan complete
