[FIX] website_sale_aplicoop: evitar sobrecálculo en precio de envío

- Ajusta _get_delivery_product_display_price para calcular envío con list_price + impuestos
- Evita aplicar reglas de pricelist al envío (recargos/descuentos no deseados)
- Mantiene fallback seguro a list_price ante errores

Resultado esperado: para PVP 5.74 con IVA 21% => 6.95
