KoalaDev d26b95985d fix(host-control-mode): only show host-control card when meaningful
The card was rendered in every room with a "Guest" badge by default — confusing
in normal rooms, and outright misleading against a relay that doesn't yet support
host control (older server omits hostPeerId, so amHost is always false and nobody
is ever recognized as host).

Now the card shows only when it's meaningful: the host always sees it (to toggle
host-only), a guest sees it only while host-only is active, and it's hidden in a
normal "everyone" room and whenever the server doesn't advertise hostPeerId
(feature unavailable). Thread hostPeerId through updateHostControlUI to detect
server support.

Note: the feature still requires the relay to run the host-control server code;
this just makes the client degrade cleanly instead of showing a stray "Guest".
