Kiosk - Remove 'Confirm' step & only have volunteers select check-in option to be fully checked in

Currently when clocking in on-site via our tablet, the volunteer checks in via their opportunity and then they need to select YES, check-in. This has led to confusion, because the volunteer thinks that they have clocked in after the initial signing. So we have volunteers that think they clocked in, but only to find when they go to clock out that they did not clock in.
