- /panel/pm: the PM app (served on the same origin under /pm) is embedded as
a full-height iframe; supervisors are funneled there from every route,
ERP MobileTabBar hidden on that route
- Panels menu: «مدیریت پروژه (PM)» is an internal route (admin/pm/supervisor
only — procurement managers do not see it); PM link is no longer external
- New system role 'supervisor' (user_role enum): label in users router,
allowed in UserRoleUpdate schema, deny-by-default on all ERP routers;
admin panel can grant/revoke it alongside procurement manager
- Removed the obsolete VITE_PM_URL build plumbing (same-origin now)
