feat(digital-id): Цифровой ID — WebView-мост к оригиналу + нативный режим

Реализован функционал Цифрового ID (паспорт, СНИЛС, ИНН, ОМС, водительское,
СТС и др.) двумя путями с переключателем в меню разработчика.

WebView-мост (по умолчанию):
- Открывает оригинальную страницу digital-id.max.ru и реализует нативный
  хост-мост window.WebViewHandler (postEvent/receiveEvent), который настоящее
  приложение MAX предоставляет нативно: lifecycle-события, биометрия,
  SecureStorage/DeviceStorage, OpenLink (переход на Госуслуги) и заворот
  OAuth-callback (externalCallback) обратно в мини-апп.
- botId Цифрового ID резолвится из settings-entry-banners конфига логина
  (как Сферум).

Нативный режим:
- DigitalIdModule — REST-клиент к ext-api.max.ru (все эндпоинты по образцу
  библиотеки gaijin: biometry, docs, esia, qr, verify, acms, profile),
  авторизация через #WebAppData= из webAppInitData.
- Модели документов и экран онбординга/просмотра.

Прочее:
- Тумблер AppDigitalIdNative (WebView/нативно) и кнопка «Сбросить Цифровой ID»
  (очистка кук и данных WebView) — в настройках разработчика.
