If auth.toml has no token, launch the Kyber AppImage as the actual user
(with DISPLAY/XAUTHORITY passed through), prompt the user to log in via
the EA Account button, then re-read auth.toml once they close Kyber.
Falls back to manual token paste if auth.toml still has nothing.
Skips the AppImage entirely on rerun when a token is already cached.
