Order Detail Provider

Single-order fetcher that watches userRoleProvider and routes to /vendor/orders/{id} for sellers, /store/orders/{id} for customers. Same family pattern is consumed by both customer and seller detail screens.

1. ref.watch(userRoleProvider) → isSeller flag.
2. OrderService.getOrder(orderId, isSeller: isSeller) hits the right endpoint with the right field selection.
3. Order goes into the FutureProvider.family cache keyed by orderId.

• Role-switch in-session invalidates the cache for this family key — the next read refetches via the right endpoint.
• Seller endpoint adds the query fields='*customer,+payment_status,*split_order_payment' to inline data the seller UI needs.

• lib/src/features/shared/orders/controllers/order_controller.dart:29 // orderDetailProvider
• lib/src/core/services/order_service.dart:44 // getOrder(isSeller)

Family providers leak entries unless invalidated — call ref.invalidate(orderDetailProvider(orderId)) after mutations.
