 - Replace `LocaleMiddleware` with `ServerRequestMiddleware`. A new class, `RequestContainer`, can be injected or retrieved from the container to get the server request. It will be `null` if the request is not defined (called before it is injected into the container by Middleware or if there's no request, e.g., a Bakery command).
