fix(blog): remove stray garden-badge includes from card footer and pagination

Three misplaced `{% include "components/garden-badge.njk" %}` calls were
rendering duplicate badges outside the post-type branches:

- One after the AI disclosure block (appeared at the bottom of every
  article card, next to "Read more")
- Two inside the pagination <nav> (between Previous/Next links)

The badge is already correctly included once per post-type branch
(article, note, like, bookmark, repost, reply, photo).
