feat: show garden badge in all post list views and overviews

- garden-badge.njk now resolves stage from post.data.gardenStage in
  list contexts (no set required), or gardenStage in post page context
- Badge added after categories in: blog, articles, notes, photos,
  bookmarks, likes, replies, reposts, recent-posts section
- Badge is clickable, links to /garden/#<stage>
