feat(c3): consulta de pedidos — schema, api, web (OrdersModule + ClientDetailPage)

- Prisma: Order, OrderItem, OrderStatusHistory + migration
- Seed: 17 pedidos em 7 clientes com itens, histórico e desnorm de clientes
- @sar/api-interface: contratos Zod (OrderSummary, OrderDetail, OrderListQuery, etc.)
- API: GET /orders, GET /orders/:id, GET /clients/:id/orders (últimos 10)
- Web: OrdersPage (lista + filtro status/número + pending_approval highlighted)
- Web: ClientDetailPage (ficha completa + últimos 10 pedidos)
- Web: /pedidos e /pedidos/$id adicionados ao router; ClientDetailPage substitui placeholder
