feat: implement instance management functionality

Added a new InstancesState class to manage game instances, including loading, creating, deleting, updating, and duplicating instances. Integrated instance selection into the game launch process, ensuring an active instance is selected before starting a game. Updated the types to include instance-related data structures.
