Reference table for bank metadata. externalId is the public bank slug —
productRouteVersionTable.bankId and friends FK to bank.id (integer);
legacy $type<string>() text columns store the literal slug with no FK.
routingNumber and fdicCert are operator-captured at create time;
nullable so seeded rows that pre-date the columns can stay valid.
