Subject: refactor(web/blog): Move atom feed creation logic to //web/blog

This was previously all inside of my personal homepage configuration,
but that's not really where it belongs.

This moves the blog post -> feed entry logic to //web/blog and moves
some other minor logic (like entry order) into the atom feed
implementation itself.
