-- Swedbank MIG rule PFH_222 (Validex round 2, 2026-08-10): when a creditor
-- postal address is present, TwnNm is mandatory from November 2026. IBAN-
-- debited payments require the address (rule 237), so items snapshot the
-- supplier's city at creation, same immutability rules as the other payee
-- fields. Nullable: suppliers without a city keep working (BGNR-debited
-- payments carry no creditor address at all).
