In Qt5 the palette was introduced in the Control object (part of Qt-
Quick-Controls-2).
In Qt6 this property was moved to the superclass 'Item'.
This means that we no longer need to refer to a control when using a
palette, every single thing in QtQuick is an Item, afterall.
It now feels like a premature optimization to make anything
that inherets from Page be wrapped in a grid layout.
Notice that a "Page" here is the thing we push on the card-stack, the
Page has the back icon and the header text.
We now hardcode the style and I needed to override the Label
in order to explicitly use the palette from the mainWindow. Not
sure why the one on Android behaved different than on Linux.
