fix: Pot and slider warnings weren't being set properly on radio or syncing with Companion (#1981)

- fix Companion yaml model read and write
- B&W radios treat bit values the same as color to avoid unnecessary complication for Companion and radio conversions
- B&W radios default is therefore off for all pots and sliders
- B&W radios fix runtime warnings check
- all radios fix to save last pot or slider position when checked and mode AUTO on change of model or power off
- all radios do not display Pots Warning in model setup if no pots or sliders supported
