WebAuthn Sign in Step 2 response

- JsonResponseWithToken
  - `meta` object, required
    - `code` integer, required — Http status code
  - `response` object, required
    - `user` object — By default an empty dictionary is returned. However by overriding _User::get_security_payload()_ any attributes of the User model can be returned.
      - `authentication_token` string — Token to be used in future token-based API calls. Note this only returned from those APIs that accept a 'include_auth_token' query param.
      - `refresh_token` string — A refresh token that can be used to get a new auth token. This is only returned if the application has enabled refresh tokens.
    - `csrf_token` string — Session CSRF token

## Other responses
