While working with Device editor user challenged for Node-RED credentials

### Current Behavior

User opens Device Editor, makes changes to flow, after a short while (10-15mins) is challenged by native Node-RED credentials (not directed to FlowFuse login page)

### Expected Behavior

Signed in users should not be presented with Node-RED credentials request

### Steps To Reproduce

unsure, I tried bouncing the forge app with a live editor session and didn't see the problem.

One guess is the time may have changed on the device, but had to verify

### Environment

- FlowFuse version: 2.9.0
- Node.js version: 18.x
- npm version: 9.x
- Platform/OS: Linux (raspberry Pi)
- Browser: NA
- Device agent version: 2.2.0
