fix(activity): word the refusals that now reach a delegate's feed

The custom-metric create and update refusals and the medication layout
refusal are filed through auditLog now, so a delegate's refused request
reaches the owner's activity feed, where it read as the generic change.
Each gets its own sentence in every bundle; the refusal sentences live in
their own function. The audit write guard states its floor, and the
schedule-reader guard names the medication create and edit, which answer
through medicationDetail.
