fix(clipboard): close popup when clicking outside

[GunawanAhmad]

Overview

Hey @Brainitech, we can't use WlrKeyboardFocus.OnDemand because keyboard navigation only works when the cursor is over the popup. I've kept WlrKeyboardFocus.Exclusive and instead followed the WallpaperPopup approach by making the popup overlay cover the entire screen.
