Delivery create now accepts externalNumber (user-supplied reference) instead
of number; the manifest number is auto-allocated server-side via
nextNumber('delivery'). Update patches externalNumber (clearable) rather than
number. DeliverySummary schema documents externalNumber and notes number is
auto-generated. Regenerate API docs.
Wire store-backed CRUD for goods receipts and suppliers, and teach the API doc generator to expand $ref/allOf/array samples so route markdown shows full JSON shapes.
