the back key: one C++ path, so a dialog closes too

A phone's back key did not close the settings dialog. A window-level QML
Shortcut never sees the key while a modal popup is up, and a desktop run says
so plainly: with the dialog open, Back left backLayer() at "settings", while
invokeMethod(win, "stepBack") closed it on the spot and Escape -- the popup's
own CloseOnEscape -- closed it too. So the key reaches the popup and never
reaches the shortcut map, which is why the drawer (no popup) closed fine and
hid the problem on a phone.

A Keys handler on the window's root item is no help either: nothing reached
it, the focused TextField keeps the key. So the key is read in C++, on the
application object but only for this window's events -- a filter installed on
the window itself was never called once, while the same key closed the drawer
through the shortcut, hence the application object.

With a layer open, the window's own backLayer() names it and stepBack() closes
it, press and release both taken; with nothing open the key is passed on
untouched, which is what leaves the window on a phone and does nothing on a
desktop. Main.qml keeps only those two functions: the Shortcut and
backHasLayer are gone, --uitest installs the same handler main() does, and the
back checks now drive the code the phone runs instead of a shortcut only the
test had.

The last check asks the phone's own question and can end the run without the
closing line -- the activity leaving takes the process with it, and every line
is flushed as it is written.

Desktop: 106 ok, 0 FAIL. Phone: 104 ok, 0 FAIL (two clipboard checks are
skipped on Android), and "after the last back: window visible 0".
