Hacky hack to make rofi-rbw typing less insane

There is some unknown interaction between `wtype` and `fcitx5`
that prevents the keyboard from being usable after wtype exits,
until fcitx5 restarts. Therefore a workaround is to use `ydotool`
to type the secrets instead.

However `ydotool` assumes an ANSI layout, which we cannot specifically
set up with niri just yet. So instead we set up a hack, to temporarily
disable fcitx & set Niri layout to ANSI right before invoking ydotool,
and reverting once it's complete.
