fix(profiles): restore single switch error toast and refetch after busy

patchProfiles entered the mutate funnel without errorNotice:false, so a
failed switch toasted twice. On busy the cached current profile was left
untouched, so a discarded switch draft could poison later clicks on the
target profile. Refetch on every non-valid outcome.
