Rework the public / status page from a flat uniform grid into a hero
featured metric plus four themed sections (Feeds, Emails, Distribution,
Instance). Add semantic colors (green success, red rejects/deletes),
relative timestamps with UTC tooltips, and derived metrics (net feeds,
acceptance rate, avg emails/feed, humanized uptime). Grid is fluid above
640px (auto-fit) and locks to two columns on mobile.
