- Навигация перенесена из левого сайдбара в ВЕРХНЮЮ горизонтальную
  панель, как в исходной программе: логотип слева, вкладки
  (иконка+подпись) по центру, пользователь+Выйти справа
- Раздел «Заказы»: мастер-детали (список слева, состав заказа справа
  с позициями и итогом), на данных /api/buyer/report
- Числовые колонки выровнены вправо (стиль DataGridCell.num)
- Отчёты: тулбар на WrapPanel, стабильные ширины колонок

Проверено запуском (скриншоты): верхняя навигация, отчёты, заказы.
