Subject: [PATCH] Show category-less posts/pages in all categories

Files without a category suffix (e.g. post.md alongside post.en.md)
previously only appeared in the default category. They now appear in
every category, so untranslated content is always visible.

- mdcms.py: nav entries with a bare variant get `uncategorized: true`;
  search.json keeps `category: null` instead of mapping to default code
- index.html: pageShouldDisplay, posts filter, and category dropdown
  all treat uncategorized/null-category items as universally visible
