Pydantic, мощь которого используется в FastAPI для валидации и сериализации, имеет специальное поведение для `Optional` или `Union[Something, None]` без значения по умолчанию.

If it doesn't receive it, it returns an HTTP 401 "Unauthorized" error.

And returns a header `WWW-Authenticate` with a value of `Basic`, and an optional `realm` parameter.

That tells the browser to show the integrated prompt for a username and password.

Then, when you type that username and password, the browser sends them in the header automatically.
