Primitive Int required widget missing

### Custom Node Testing

- [ ] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

when exporting API, the "control_after_generate" widget should be exported as well, otherwise if you import a png the value might become randomized

### Actual Behavior

you drag in a json or png with API workflow stored in and the primitiveInt nodes have randomized values

### Steps to Reproduce

just export a dummy workflow and reimport it

### Debug Logs

```powershell
