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.
A peer that has not yet handshaked is now show in this view, giving a
better indication of what is going on on platforms that do not have easy
access to a log file.
This is likely the oldest component in the app and it was
really in need of a rewrite.
The state of peers is shown much clearer now, we use a proper
model in order to avoid the jumping and we use a more safe
way of getting at the data.
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.
