- PaymentService (order lifecycle, fulfillment, refund 3-phase)
- PaymentConfigService (settings, instance/channel/plan CRUD)
- 31 API endpoints (9 user + 4 webhook + 18 admin)
- Wire DI integration

Frontend (Vue3):
- Payment types, API modules, store, router changes
- Sidebar: payment_enabled controls visibility, new menu items
- User pages: PaymentView (replace iframe), QR payment, Stripe,
  result page, order list
- Admin pages: Order management (4 tabs), provider instance mgmt
- Settings: new payment tab, removed old purchase iframe config
