The $.psc.blogcomment widget (from the removed wwwroot/js/comment.js)
provided reply-to-comment nesting. Rewrite Details.cshtml to drive the
same /api/v1/blogcomments endpoint with ParentId, delegating reply
clicks so they work across the whole nested tree.
Render comment metadata server-side in the Comment view component
template (the widget used to add it client-side) and Include Author so
nested comments get their author instead of relying on the request-scoped
identity map.
