The APScheduler cron job fires daily at every entry in `periodic_times`,
and nothing in the dispatch path consulted `periodic_interval_days` or
`periodic_start_date` — so a configured 3-day interval still produced a
daily summary.
Gate the dispatch in `dispatch_scheduled_for_tracker` for kind=periodic
via `(today_in_app_tz - start_date).days % interval == 0`. Log a skip
with reason `interval_not_due` on non-firing days so operators can tell
suppressed-by-interval apart from other skip causes.
