Subject: fix(hub): Explore page says nothing about public groups when they're
 off
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the hub has public groups disabled, /explore showed an empty "Public
Groups" screen with a search box and a Create button that do nothing. It now
renders a single line — "This hub does not have public groups." — and the
server already returns an empty directory regardless.
