Why this exists

Tariffs, RFQs, bookings, and Control Tower still store many lane and party fields as free text (for example originCode, carrier, countryCode). This catalog gives you a single place to normalize ISO countries, ocean SCACs, and airline IATA + AWB prefixes before we wire FKs and validation into each module.

• Tariffs / geography: align TariffGeographyMember.memberCode and legal-entity countryCode with ISO alpha-2 from here.
• Logistics: tenant LocationCode.countryCode and warehouse country fields should match these codes.
• Next steps (not done in this pass): optional FK from ShipmentBooking to UN/LOCODE rows; carrier SCAC on contracts; AWB validation for air milestones.

Seeded counts — countries: 0, ocean carriers: 0, airlines: 0. Re-run npm run db:seed to refresh catalog rows (upserts).
