Group check-in capability

To be able to do a group checkin all at once. (What if there is no ID? Warning and continue the same) - In the future it would be nice to create a TO-DO to remind you that you have to scan the guests that you missed. (Raise a modal and mark all reservations that meet the conditions, the checkin button will be in the footer, touching the reservation will go to the details and checkin there will jump the same modal of the group. (modal similar to scan, with reservations that already have disabled type checkin) (Two tabs: (reservations and conflicts, that in conflicts can operate)
