feat(blog): move "About the author" card to the bottom of each post (#8060)

Relocate the per-post AuthorBio ("About the author") card from just below
the header to the end of the article, after the body and before the
series/related-posts section, so readers meet the author credentials
right after finishing the post. The compact byline (avatars + date) stays
in the header. Update the placement comments to match.
