+/**
+ * lunarphp/stripe's own stripe_payment_intents table already correlates a
+ * Stripe intent back to a cart/order via cart_id/order_id — exactly what
+ * Modules\Core\Payment\Drivers\StripePaymentDriver needs to recover
+ * $context in handleCallback(), a separate request (a webhook) from the
+ * pay()/authorize() call that originated it. Two columns this driver
+ * needs that the vendor table doesn't have:
+ *   - context: the full opaque $context bag pay()/authorize() received,
+ *     stored so handleCallback() can dispatch the SAME context the
+ *     original call would have, without Payment inventing its own
+ *     correlation table — see docs/payments.md "Async resolution".
+ *   - payment_type: the payment type key (e.g. 'stripe') pay()/authorize()
+ *     were called with — needed to dispatch Payment events with the
+ *     correct $type in handleCallback(), which otherwise has no way to
+ *     know it (a webhook payload doesn't carry it).
