On the desktop activity view the prices are right aligned but due to
adding fiat prices this means that the bch amounts are not lining up.
This adds a little space between the two in order to make them much more
readable.
The idea is that if you send a transaction you may want to see it
getting confirmed.
This now shows directly in the main UI in an unobtrusive manner with
checks.
This moves the heuristic to exist only once and avoids duplicating it.
Additionally this increases the checks accuracy.
Last, the 'moved' price in desktop now is white to indicate it is
not a balance change.
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.
