CHW-1202 GlobalAdminRequired

global admin privileges are required to assign or modify the global-admin role

Default message: global admin privileges are required to assign or modify the global-admin role
HTTP status: 403 (client)

Problem. The caller tried to assign, modify, or remove the global-admin role without being a global admin themselves. Cause. Global-admin is a cross-org superuser tier; it can only be granted by an existing global admin. Fix. Ask a global admin to perform the change. HTTP 403.
