// ProviderOrder stores provider-specific checkout data for one internal order
// row. For OkPay this is expected to bind to the concrete child order created
// by switch-network, not to the parent merchant order.
//
// Binding rules:
//   - trade_id always points to orders.trade_id
//   - the bound orders row should use the same pay_provider value
//   - provider identifies which downstream checkout created the provider row
//   - provider_order_id is the provider's own order number (for OkPay this is
//     the returned order_id from /payLink)
//   - pay_url is the hosted payment URL returned by the provider
//
// The main orders table remains the source of truth for merchant-facing state,
// while this table keeps provider-specific identifiers and callback payloads.
