 * Reservation (paid shipment) quota for the current plan.
 *
 * The free (Bronze) plan is limited to a number of PAID reservations per year
 * (`maxShipmentsPerYear`, e.g. 5); higher plans are unlimited. The value comes
 * from the backend, which uses the organization's real plan (not the ADMIN
 * PLATINIUM override) and counts only paid shipments — so the UI can prompt an
 * upgrade once the limit is reached instead of failing at the end of the flow.
