feat (moes_zcjk_alarmclock): attempt to better handle the color loop effect

Show color loop as an effect instead of as the color white.
- hide white from the list of colors, but support reporting it because we need to report something.
- add an effect of loop, choose red when turning the effect off, because we have to select something.
