[Bug]: Zoom level is not restored when loading workflows

[christian-byrne]

Frontend Version

1.7.14

Expected Behavior

When the "Comfy.EnableWorkflowViewRestore" setting is enabled, the zoom level (scale) should be serialized and restored.

Actual Behavior

When saving workflows, the offset is serialized and restored but the zoom level (scale) is always 1.

Steps to Reproduce

1. "Comfy.EnableWorkflowViewRestore"
2. Create a new workflow
3. Zoom out or in
4. Save the workflow
5. Close the workflow
6. Load the workflow
7. Observe zoom is not restored

The issue actually only occurs if changing the zoom level was the last change made to workflow before saving, as it's not a tracked change:

https://github.com/Comfy-Org/ComfyUI_frontend/blob/816574e0aba1425bcc047f0dcf3198e4abd1441a/src/scripts/changeTracker.ts#L393-L397

All solutions to this edge case that I can think of would not be worth the added overhead.
