/**
 * Handles the notification actions. The dose card groups every med due at the
 * same wall-clock minute, so its buttons act on the whole occurrence (carried
 * as EXTRA_SCHEDULED_AT), not a single log — "Tatt alle" / "Utsett alle".
 *
 * Contract (CLAUDE.md, load-bearing), applied to each dose in the occurrence:
 * - Taken  → TAKEN, decrement inventory by the *logged* amount, stop escalating.
 * - Snooze → SNOOZED, next nag in 15 min, keeps escalating (and counting) after.
 * - Mute   → "Ikke forstyrr": stop escalating, dose stays unresolved.
 * (Skip stays a per-dose UI action; the notification never offers it.)
