Description
When a metrics server crashes (process exits), clicking "Stop" in the UI fails silently — ECONNREFUSED on the stop request leaves monitorRunning: true in the frontend, causing a stuck banner.
In runMonitorForNode, when a stop request fails (catch block), send monitorFulfilled with monitorRunning: false instead of monitorError. The metrics server is dead, so monitor is effectively stopped. Start request errors still report as monitorError.
