fix(web): correct blog colors for the light workspace + thumbnails

Only the .rail sidebar is dark; the .workspace content area is on the
light (#f6f7f4) page background. The previous blog styling assumed a dark
workspace, so text was light-grey on white (unreadable) and the link
green was too light.

- Darken the global link color to #0a7d59 (readable on white); content
  links only — rail nav stays inherited.
- Repaint .blog-content (post HTML) for a light surface: dark body text,
  light code/pre, light borders.
- Blog index/post: dark titles, readable grey meta, light row borders;
  light-themed footer.
- Add post thumbnails to the /blog index from featured_image.url.
