/**
 * Migration 20260904001000 (#2181): the InboundMailReceived catalog row, and
 * the per-attachment idempotency index on invoice_inbox_items becoming
 * company-scoped so one mail addressed to two inboxes files once per inbox.
 * tests/pg/processing-event-types.pg.test.ts already proves every emitted
 * type is registered; this file pins the two behaviours the webhook now
 * relies on.
