fix: set body_html on mock response; remove dangling log assertion

- _make_mock_llm_response now sets body_html/raw_text (not just text).
  _create_blog_post writes body_html into blog.post.content; an unset
  MagicMock attr stringified to ~66 chars, failing the 500-char assertion.
- Remove leftover `assert log.tokens_used` in then_tokens_used_recorded
  that referenced a variable deleted in the prior router-level rewrite.

Full suite: 69 passed, 0 failed.
