feat(apns): time-sensitive interruption-level for medication reminders

Medication reminders are the one notification category the user has
explicitly opted in to. iOS 15+ supports `aps.interruption-level:
time-sensitive` to break through Focus modes per category, gated on
a per-app toggle the user grants on install. Wire it for
MEDICATION_REMINDER only — every other event (mood nudges, anomaly
alerts, PRs, system messages) stays on the iOS default `active`
level so Focus modes including Sleep keep silencing them as the user
expects.

Pairs with `apns-priority: 10` for time-sensitive deliveries per
Apple's push best-practices doc; without the priority pairing APNs
may downgrade delivery and silently lose the Focus-bypass intent.

Pinned by 8 new unit tests across `apns.test.ts` — one positive case
for MEDICATION_REMINDER and a parameterised negative covering all
six other event-types.
