[Support] If the header or footer is absent, a guide assertion failure occurs.

배경

API declaration order is important when configuring header and footer, but there is a possibility of human error.

❌

    .willDisplayHeader {
      ...
    }
    .withHeader(
      Some()
    )

⭕

    .withHeader(
      Some()
    )
    .willDisplayHeader {
      ...
    }

• So, If the header or footer is absent, a guide assertion failure occurs.
