fix: propagate widget disabled state to Vue node components (#9321)

## Summary

Widgets with `widget.disabled = true` (e.g. display-only counters in
custom nodes) were editable in Vue node mode despite being correctly
greyed out in litegraph mode. The disabled state from the widget store
was not being merged into the options passed to Vue widget components.
