`medication.clientManaged` and `measurementReminder.clientManaged` mean
the iOS client schedules the reminder locally, so the server should not
push it. That is what the OpenAPI description, the settings copy and the
iOS contract all say. What the crons did was skip the dispatch entirely,
so a user who flipped the switch also lost Telegram, ntfy, webhook,
email and Web Push — channels they may well read on a desktop while the
phone holding the local schedule sits in a drawer.
Move the gate into the dispatcher's channel loop, where it applies to
APNs and nothing else. The skip is not counted as an attempt, so
`dispatched` keeps meaning "something reached the user", and it stays
countable: the same wide-event keys the crons emitted are emitted here,
plus a `skipped` row in the push-attempt ledger.
The Vorsorge path is the sharper half. It suppressed every channel and
then advanced `nextDueAt`, which dropped the reminder out of the
preventive-care card and out of the daily digest: a reminder that never
reached anyone was recorded as handled. The advance now happens only
where it always belonged, after a dispatch that a channel actually
delivered. When nothing delivers, the reminder stays overdue and visible.
