/** Reload a LIVE node's credentials over its view.sock. Connects as an OBSERVER

 *  the fan; the broker's reload_auth handler is open to any client), sends
 *  `reload_auth`, and resolves on its ack. Rejects on the broker's `error` frame,
 *  connect failure, a premature close, or timeout — the caller (the daemon fan)
 *  isolates each broker so one failure never aborts the rest. */
