+/**
+ * The legacy `send_stop_blast` RPC constructed a `communication_campaigns`
+ * row whose audience was a stop and dispatched Resend emails. The new
+ * schema has no `communication_campaigns` table, no `stops.orders` join,
+ * and no per-recipient log. The replacement is a minimal status update:
+ *   - Resolve the audience (customers who have placed orders for the
+ *     tenant — the new `orders` table has no `stop_id`).
+ *   - Insert a draft `campaigns` row to act as the campaign id.
+ *   - Return the count and the new id. Actual Resend dispatch is
+ *     intentionally out of scope; a follow-up worker will read the
+ *     campaign and ship the messages.
