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.
