Renders the same Live Stats / channels table that `websockets:info` shows
at the bottom, but loops indefinitely so it can be left open as a quick
status pane. 1-second poll against the existing WebsocketService cache
reads — no pub/sub plumbing because there is no "stats changed" event
emitted today and a 1s tick is fast enough for the granularity humans
care about.

+ * Live-updating display of WebSocket connection stats.
+ *
+ * Renders only the stats portion of `websockets:info` (total connections,
+ * authenticated users, active channels, per-channel breakdown) and refreshes
+ * every second by default.
+ *
+ * Polling vs. event-driven: stats live in the cache store (Redis in prod) and
+ * are written by the running websocket process. There is no pub/sub channel
+ * that emits a "stats changed" event, so a true event-driven approach would
+ * require either tailing the cache writes or adding pub/sub plumbing into
+ * WebsocketService. A 1-second poll is well under the granularity at which
+ * connection counts are interesting and avoids that infrastructure cost.
