Add cart-mini + auth-menu fragments to all apps, fix like button

- Market, events, federation, account now fetch cart-mini, auth-menu,
  and nav-tree fragments concurrently (matching blog's pattern)
- Move like button template to shared/browser/templates/ so blog can
  find it without needing market's templates in its container
