Hotfix 0.9.1

- Fixed several issues that could block progression during the prologue. In some cases, if the first customers were not seated quickly enough, they could leave the reception area and never return during the current playthrough. Another issue could occur if the player let time pass until the end of the day, preventing the prologue from progressing. Time is now frozen at 10:00 AM for the first customer group and at 4:00 PM for the second group, giving players enough time to complete each tutorial step. Once these objectives are completed, time automatically advances to the end of the day so progression can continue normally.
