fix: use WidgetSelectDropdown for models (#6607)

## Summary

As the commit says, the model loaders were broken in cloud if you
enabled Vue Nodes (not a thing I think user does yet).

This fixes it by configuring the `WidgetSelectDropdown` to load so the
user load models like they would load a input or output asset.

## Review Focus

Probably `useAssetWidgetData` to make sure it's idomatic.

This part of
[assetsStore](https://github.com/Comfy-Org/ComfyUI_frontend/pull/6607/files#diff-18a5914c9f12c16d9c9c3a9f6d0e203a9c00598414d3d1c8637da9ca77339d83R158-R234)
as well.
