Fix ScreenChooserDialog Layout
contentWidth and contentHeight of ScrollView must be set when more than one item is used. (https://doc.qt.io/qt-6/qml-qtquick-controls-scrollview.html) This was not needed before porting from Kirigami.CardsGridView to Kirigami.CardsLayout in ebfeb51f since CardsGridView was just one item.
Set Layout.preferredHeight of PipeWireDelegate so preview image has enough vertical space.
