Add release date/publisher/size info and a noVNC link to the setup page

Manifests gain release_date/publisher fields (static historical facts).
Install size deliberately isn't a manifest field - get_zip_sizes() looks
it up live via a batched smbclient ls (one call per game, single
connection, split on each command's trailer line) so it can't go stale
if a zip is replaced.

Add an "Open noVNC Screen" link at the top of the page. Its href is set
by a few lines of client-side JS reading window.location.hostname at
render time, since the noVNC port (NOVNC_PORT, now passed into
setup_server.py by server.sh alongside SETUP_PORT) differs from the
setup port and the container may be reached via different
hostnames/IPs - a fixed server-rendered URL would be wrong.
