Marc-André Bombeck b9b38d182c feat(notifications): coalesce the intake sync push per user and strip its payload
The MEDICATION_INTAKE_SYNC fan-out used to fire one silent APNs per
distinct dose slot, so a bulk intake marking five doses woke every other
device five times. Replace the per-slot dispatch with a per-user
coalescer: the first mutation in a burst dispatches immediately, every
further mutation inside the 2 s window folds into one trailing fan-out.
A bulk request now costs exactly one queue call, and a rapid burst of N
single-dose mutations costs at most two fan-outs. The window state is
in-process; multiple app instances throttle independently, which is
accepted because the iOS reconcile is idempotent and the deployment
model is a single container.

The silent payload shrinks to a pure sync trigger — eventType +
syncedAt. The per-slot medicationId / scheduledFor fields are gone: the
iOS handler runs a full reconcile regardless, a coalesced burst has no
single slot to name, and a push payload travels through Apple's
infrastructure, so it now carries no health data by construction. The
Live Activity end push likewise sends only the ActivityKit envelope.

The trailing flush keeps the origin skip only when every coalesced
mutation came from the same device; a mixed-origin burst wakes everyone.
Each flush still records one push_attempts ledger row, reaps
hard-rejected device tokens, and annotates the wide event with the
recipient count and coalesced-mutation count.
