Menu popup leaks when the activity finishes with the menu open (WindowLeaked) #205

From a tester's log (OPPO CPH2725, Android 15, toy test build 8aaf666, #187):

E WindowManager: android.view.WindowLeaked: Activity com.openipc.decoder.Decoder has leaked window android.widget.PopupWindow$PopupDecorView{… 0,0-688,264 …}
  at android.widget.PopupWindow.showAtLocation(PopupWindow.java:1322)
  at a.w1.j(…)                    → MenuManager (show the menu)
  at a.o0.onSingleTapConfirmed(…) → Decoder$5 (a tap on the picture)

(retraced with that build's mapping.txt)

The activity finished while the menu popup was still showing, for example after Exit in the menu or Back. It isn't a crash: Android removes the window and logs the leak. But the popup should be dismissed before the activity goes away.

Fix: dismiss the menu popup in onDestroy (and before finish() from Exit); check the Reset dialog the same way.
