Subject: [PATCH] feat: add POST /api/payment/{orderId}/pay mock payment
 endpoint
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- PaymentController: @RestController at /api/payment, requires
  authentication (covered by SecurityConfig.anyRequest().authenticated())
- POST /{orderId}/pay: calls orderService.markAsPaid(orderId) which
  sets status=PAID and amountPaid=49.00, returns updated OrderResponse
- No Stripe integration yet — pure mock simulating what a successful
  Stripe webhook callback would do in Phase 1
- toResponse() mapper reuses the same OrderResponse structure as
  OrderController for consistent API shape
