Adds DJF to freight.payments_currency_enum (migration 3860000000000, alone in its own migration per Postgres's ADD VALUE-in-a-transaction restriction) and to manual_payment_settings (djf_enabled column, migration 3870000000000, default true). Replaces the binary ETB/USD assumptions that would have silently mispriced or discarded a DJF booking: - booking-pricing / contract-pricing: usdToEtb scalar -> a rate table keyed by source currency (ExchangeService.getRateTable), so a contract-frozen rate converts into whatever currency the booking is paid in instead of being dropped when neither leg is ETB or USD. - warehouse-fee / booking-wagon-cancellation: normalizeCurrency no longer coerces anything non-ETB to USD. - additional-charge: convertAmount no longer bails out for a currency that isn't literally ETB or USD. - manual-payment-settings: isEnabled/enabledCurrencies cover DJF. Widens the three @IsIn(['ETB','USD']) DTO validators, and adds DJF to the export/report currency filter option lists. Claude-Session: https://claude.ai/code/session_01CZy77vCWhka3pnmVF9NDkL

|
* This statement must be the ONLY thing in its migration: `ALTER TYPE ... ADD

* transaction (`migrationsTransactionMode: 'each'`). Do not add a seed insert
