OrderPaid was defined but never dispatched. Order::booted() now fires it from
the `updated` hook exactly when paid_at goes null -> value (recordPayment()
reaching amount_total, the Stripe checkout webhook, or a direct update). Later
saves of a paid order, partial payments and overpayments do not re-fire it, and
a host subclass configured via shop.models.order gets it with its own instance.
StripeWebhookController, ShopService and Cart::checkout used the base
Blax\Shop\Models\Order statically (createFromCart, find, where, scopes,
aggregates), so a host app's configured Order subclass — with its own boot
hooks — was bypassed on the real webhook path. They now resolve
config('shop.models.order') through a small orderModel() helper. Return types
are unchanged (subclass instances satisfy Order); Order::formatMoney stays a
pure static.
Tests: OrderPaidEventTest (once-only on recordPayment, partial payments,
direct paid_at update, host subclass) and StripeWebhookOrderModelTest
(handleCheckoutSessionCompleted builds the configured subclass and its boot
hook runs; webhook/ShopService/Cart finders return it). Suite: 1485 tests green.
