configure.py: three new host roles (files/sync/clips) in --full, --hosts, .env, Caddy generator;
main host serves about/ at the root (/about* redirects); /time only where it is fetched same-origin.
about/index.html links across hosts; addCommunityMediaServer.sh asks for the new names; Caddyfile.example
regenerated; README/FRESH-INSTALL/HOSTNAME-CHANGE (procedure C)/STATUS updated.
