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 follows the re-designed the 'import wallet' to
now have the same design and featureset from mobile also on
desktop.
The 'new-wallet' pages in general have also been changed as to
avoid wasting most of the space on the advertisment style
content and aim to have a vertical design so we avoid forcing
people having to scroll.
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.
