Administrator scope for pending assignment review

For the established (legacy) Volunteer Management portal. These steps differ from the newer Volunteer Management interface. Staff access is determined by their assigned administrator role(s). Administrator roles have fixed capabilities; the configurable volunteer roles described here are separate from staff administrator roles.

Pending assignment review can be restricted to volunteers associated with the VMS administrator. If one administrator does not see a request, verify that it was created, remains pending, and belongs to that administrator's volunteer scope and intended role/unit before concluding it disappeared.
