- Сервер: /api/me отдаёт retailPointIds (точки, к которым привязан сотрудник). - Касса: DeviceRegistration (чистая логика, 5 unit-тестов) — первый запуск: админ выбирает точку из списка активных (сохраняется на устройстве, kv); кассир на незарегистрированном устройстве → «обратитесь к администратору»; кассир, не привязанный к точке устройства → «вы не привязаны к этой кассе»; админ работает на любой точке. Смена точки — кнопка-сброс (новую выберет только админ). Экран входа: шаг выбора точки (ComboBox активных точек). - Заменяет прежний «берётся первая активная» (ошибка при двух точках). - Тесты: unit (5 решений гейта) + integration (/api/me retailPointIds кассира).
