Avalonia: Прайс-лист как в WinForms — дрилдаун Название→МГ→Предложения + ввод количества с клавиатуры

- База/дозировка вычисляются на клиенте (порт BuildBaseName/ExtractDosage)
- Три панели: базовые наименования → дозировки (МГ) → предложения поставщиков
- Колонка «Заказ»: ввод числа с клавиатуры (многозначно), Enter — добавить
- Фикс: null-безопасная привязка KeyDown (падало в конструкторе → пустой экран)

+| ✅ Справочник | профиль + грузополучатели | готово |
+| ✅ Отправить | поиск → корзина → создание заказа (POST /api/buyer/orders) | готов UI; реальная отправка не тестировалась (создаёт заказ на проде) |
+| ⏳ Отказы | список отказных позиций | нужен серверный эндпоинт (RefuseItemsCount есть только в локальной БД WinForms) |

-**Порядок рекомендую:** Заказы → Прайс-лист → Отправить → остальное.
-Бизнес-логика каждого — обычный C#, переносится как есть; переписывается
-только UI (WinForms → Avalonia XAML), что и есть основная работа.
+**Прайс-лист/Заказы/Накладные** строятся на рабочих эндпоинтах
+(`supplier-prices/summary`, `buyer/report`). «Родные» `buyer/orders` и
+`buyer/catalog` возвращают 500 (баг квотинга PascalCase в GORM-билдере).
+Фикс для **buyer/orders** готов и застейджен (`es_api_service.exe.new`,
+apply-new-exe.bat) — после деплоя Заказы/Накладные перейдут на него.
+Каталог не используется (берём рабочий summary), его фикс — по желанию.
+
+Осталось: **Отправить** (корзина + создание заказа + DBF) и **Отказы**,
+плюс автообновление и сохранение сессии. Логика переносится из WinForms,
+переписывается только UI (XAML).
