stop creating Product_Member / Product_Type_Member during auto_create_context

The scan-import auto-create flow no longer bootstraps Owner RBAC rows
inline. Pro's post_save signals on Product and Product_Type take care of
this on any newly created instance. Drop the Product_Member,
Product_Type_Member, Role, get_current_user imports — they're unused now.
