The socket had no recovery path: a mid-game drop left the table showing
stale state with no indication, and plays were silently swallowed by the
dead channel. Surface the server close code from ws::connect and add a
reconnect driver in the game page: transient losses retry with
exponential backoff (capped, then a manual Retry), while deliberate
closes (session expired, game gone) stop retrying. Reconnects are free
resyncs because the server pushes a full state snapshot on connect.
Also gate card clicks while disconnected, show a connection banner, and
drop the ticking interval and pending retries on unmount.
