The non-themed import basically is just a proxy using some
auto-detection to find out which theme to use.
As the app only uses the basic theme, this is what we'll import.
Seems that the problem we saw on Android is also present on
Linux and Wayland.
A lot of components no longer use the palette which makes it
not possible to use them as-is with our light/dark theme feature.
This changes the many components to the Flowee specific ones
where we already solved this for the Android UI.
This exports the payment-request address to the QML side.
We use this to show under the QR the address we are requesting to send
to.
This is quite useful for users wanting to manually check if things are
going well.
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.
