Allow room move on departure day

It can happen that after midnight for some reason a room move is required but it's also the day of departure. Previously it was not possible to perform a room move in such scenarios. We extend the room move logic to also support room moves on the departure date.

The following logic is implemented:

• A new reservation is created for the new room with:
  
  
  1. Arrival date = yesterday
     
  2. Departure date  = today
     

• The old reservation is updated as follows:
  
  
  • If the guest was checked in → the departure date is set to yesterday.
    
  • If the guest’s arrival was also yesterday → the old reservation is cancelled instead.
