User must have global access to update global categories

The user's global access level must be >= $g_manage_site_threshold to
be allowed to add, edit or delete global categories.

Prior to this, once a user had been defined as Manager on at least one
project, they could freely update global categories.

Also prevents such updates through URL manipulation.

Fixes #13561
