feat(order-detail): collapsible order composition with table layout

- Extracted IIFE into CollapsibleOrderComposition component to fix React hooks error
- Состав заказа свернут по умолчанию, разворачивается по клику
- Позиции отображаются в табличном виде (grid 1fr + auto)
- Количество и единицы измерения не обрезаются (whitespace-nowrap)
- Парсинг работает из source_orders, order_list, order_list_structured
