Add the settings to Compass' preferences schema. We'll want to update how CompassWeb handles its preferences (they're currently read-only) to be able to save the user setting when a user will opt-in (the opt-in modal is added in the next ticket).

The org settings override the group (project) settings. This ticket does not involve passing these in yet from the mms frontend, just default them to off.
