Fix configuration changes received by QSFragmentCompose

The fragment was only receiving configuration changes from the default display, as FragmentService propagates only from the default configuration controller.

This sends the configuration from the @ShadeDisplayAware configuration controller instead.

We can't refactor FragmentService to send the shade config for now as there is also a statusbar class using it (but it will soon not be needed for statusbar anymore and we could fix it upstream there)

Note this is only needed in pre-flexiglass.

Bug: 437892388
Test: connect external display, enable dsktop mode, open shade on external display, unfold device, open shade on built-in display, check the size of QS is correct
Flag: NONE - bugfix
