fix(airconditioner): Good Sleep needs the mode token its duration belongs to

Sleep_<n> written on its own is answered 2.04 Changed and then discarded, so
the Number wrote nothing at all. Nano wind shares the same Comode_ slot, which
is why writing the nano preset over a running timer silently changed its
duration, and why the two sleep codes the board reports had to become presets:
a preset_mode outside preset_modes is not a state HA allows.
