Craft CMS: Missing authorization check allows non-admin control panel users to reorder Global Sets

The `reorder-sets` action in Craft CMS’s `GlobalsController` is missing the `requireAdmin()` check that the adjacent `save-set` and `delete-set` actions both enforce. Any authenticated control panel user can POST to `/actions/globals/reorder-sets` and permanently reorder all global sets in the project config, regardless of whether they have admin access. The reordering is written through to the project config and persists across requests. ## Description `GlobalsController` exposes three administrative actions for managing global set structure. Two of them gate on admin status; the third does not. ## Prerequisites - A Craft CMS instance with at least two global sets and a non-admin control panel user account. ## Impact A non-admin control panel user can reorder all global sets. While this does not expose or modify content, reordering global sets modifies the project config -- a versioned artifact that is typically committed to source control and deployed across environments. An attacker can create noise in the project config history, trigger config-sync conflicts, or manipulate the display order seen by all editors in the admin panel. The same non-admin user cannot create or delete global sets because those actions correctly enforce `requireAdmin()`.
