feat(settings): say that the daily briefing reasons at its own depth

The provider's reasoning select reaches neither the Coach nor the
background jobs: the daily briefing thinks at Medium at most, lower under
the operator's cap, and not at all on the Frugal usage level. A line under
the select now says so, in every locale. Behaviour is unchanged.
