fix(cli): stub out the onboarding service install

Quick mitigation: the onboarding service step kept shipping broken
first runs (#12148, #12153, #12155). Comment out the call at both
onboard sites so onboarding configures and offers a foreground start
again; the module, its tests, and the flags stay in place for the
rework. Park the smoke_service release gate with if false since the
flag it drives is inert, and pin the disable in the shape test.
