[FIX] TestConfirmEskaera_Integration: limpieza de decoradores @patch y corrección de bugs

- Convertir 4 tests de decorador @patch a context manager 'with patch(...)' para evitar RuntimeError en LocalProxy de Werkzeug
- Corregir patrón env(user=..., context=dict(...)) en Odoo 18 (sin .with_context())
- Agregar website real al mock para integración con helpers de pricing (_get_pricing_info)
- Añadir pickup_date en fixture de existing_order para que _find_recent_draft_order localice correctamente
- BUGFIX: Agregar (5,) a order_line para limpiar líneas previas al actualizar pedido existente

Resultado: 0 failed, 0 errors de 4 tests en Docker para TestConfirmEskaera_Integration

BREAKING: _create_or_update_sale_order ahora limpia las líneas anteriores con (5,) antes de asignar las nuevas cuando se actualiza un pedido existente. Comportamiento previo (duplicación de líneas) era un bug.
