Fix: remove duplicate author-bio includes, add author images, move inline styles

- Remove author-bio.php and article-footer.php duplicate inclusions from
  inside related article cards across 17 articles (was rendering 4x per page)
- Create /assets/images/authors/ with SVG avatars for all 7 named authors
- Move inline <style> block out of author-bio.php into main.css

assets/css/main.css
