fix(medications): key the dedup pin guard on persisted attribution, not a timestamp shape

Every standalone intake anchors its slot on the take time since
v1.15.19, so guarding the nightly dedup on that shape excluded ordinary
drift duplicates from collapsing — the original point of the sweep.
Releasing a pinned dose now persists the user's choice on the row, the
dedup and the repair script key their exclusion on that flag, the read
model reports a released row as deliberately off-schedule instead of
re-snapping it within the anchor epsilon, and the attributed badge only
shows on rows actually bound to a slot. A few fixture names and stray
comments also drop personal references.
