/**
 * The customs clearance service fee is no longer prepaid via its own
 * `clearance`-source invoice — it is billed as a CUSTOMS_CLEARANCE line on the
 * booking invoice, together with the freight (see BookingPricingService).
 *
 * - Contracts/bookings parked at the payment gate move straight to the
 *   document step (the gate no longer exists — nothing could ever pay them).
 * - Open (unpaid) clearance invoices are expired; PAID ones stay as history.
 *   NOTE: a ONE_TIME customs contract that already PAID its prepaid fee but
 *   has not booked yet will be billed the fee again on its booking invoice —
 *   accepted for dev data; reverses the old AddClearanceFeePayment migration.
 * - clearance_fee_paid_at columns are dropped from contracts and bookings.
