Read-only models cannot be pinned from workspace

[profoundvision]

Hi,

A small issue but annoying for our users: since the new update showing some models in the workspace as read only, they cannot pin models here anymore.

I know you can still pin them from the model selector but it is more intuitive to do it from the workspace tab.

Additionally they cannot clone models anymore, which I think is still useful even if they cannot edit or delete models not owned by them.
