Covers NOTIFY-01/03: due-date selection (daily always, weekly only on
Monday Europe/Berlin, off never, missing pref row defaults to daily —
D-01), multi-tenant safety via findMany over ALL due users across ALL
tenants (never findFirst — the documented DkvSchedulerService v1-gap,
Pitfall 1), one sectioned mail per user grouping matches by saved
search (D-02), the no-double-send notifiedAt eligibility gate (only
notifiedAt=NULL selected, stamped notifiedAt+channel=digest only after
a successful send — D-06), and per-user robustness so one failing/
skipped/throwing user never aborts the run for the rest (Pitfall 6).
