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 detects that the currently selected wallet is fully encryted and if
it is, it shows a password request page on top of the current screen.
The default setup aims to have people type a PIN in numbers to unlock
the wallet, but we also provide a way to make it use a textual password
instead.
