Adds an anonymous guest checkout flow so a customer can order a bilhälsning
without creating an account. Payment via Swish (QR + payment link).
Backend:
- GuestOrderController: POST /api/guest-orders (public, no auth)
- CreateGuestOrderRequest / GuestOrderResponse DTOs
- Order entity: guest_email, guest_token (UUID), nullable user_id
- OrderRepository: findByGuestToken, findByGuestEmail
- OrderService: createGuestOrder, getGuestOrder by token
- SecurityConfig: /api/guest-orders/** permitAll
- V12 migration: drops user_id NOT NULL, adds guest_email + guest_token
with partial unique index (backfill-safe for existing user orders)
Frontend:
- GuestCheckoutPage: plate lookup + order form (no login)
- GuestPaymentRedirect: Swish QR + payment link + status polling
- GuestOrderPage: order status by guest token
- guestOrders.ts API client
- router: /guest/* public routes
- vite.config: dev proxy for /api/guest-orders
Verification:
- [x] vue-tsc type-check passes (exit 0)
- [ ] Backend Java compiles (no JDK/docker in agent sandbox)
- [ ] Flyway V12 migration applies cleanly
- [ ] End-to-end POST /api/guest-orders -> 201 -> Swish -> status
Frontend type-checks but backend has NOT been compiled or run yet. This
PR is for review; backend smoke test pending in a docker environment.
