Total price adjustment for group bookings

The new functionality to edit the total price of the reservation is currently intended only for individual reservations.

• In group bookings, the location of the functionality is within each partial booking. Which may be fine, but for a general adjustment it does not work.

• The interesting thing is to be able to adjust the price (either increase or discount) of the total reservation, in a quick way. When working with groups of many rooms this is essential to try to close the final price, or even make minimum rounding of the total.
