+ * Phase 5 — Automated billing cron logic.
+ *
+ * This module hosts the two sweeps:
+ *   - runMonthlyIssuance() — invoked monthly to generate invoices
+ *     for orgs opted into auto-issuance. Idempotent via the
+ *     uniq_invoices_org_period constraint on invoices: a re-run
+ *     for an org that's already been billed for the target period
+ *     gets caught as a duplicate and counted as a skip, not a
+ *     failure.
+ *   - runReminderSweep() — invoked daily. Walks open/overdue
+ *     invoices, sends the appropriate reminder level (1/2/3) once
+ *     per invoice via the invoice_reminders unique-key constraint.
+ *
+ * Both entry points return a summary {success, failure, skipped}
+ * that the caller persists via finishCronRun(). The shared
+ * structure means the HTTP routes (machine + admin variants) are
+ * trivial wrappers.
+ *
+ * Time-of-month math is timezone-aware: we read the calendar in
+ * Europe/Zurich rather than UTC, because the K8s CronJob schedules
+ * at 00:30 local time on the 1st — UTC at that moment is still in
+ * the previous month, and a naive `getUTCMonth() - 1` would bill
+ * the wrong period.
