Refactor and reorganize scripts for improved structure and functionality

- Removed obsolete scripts: Chest, BreakableWall, Door, DoorInteract, and UiManager.
- Moved Chest and BreakableWall scripts to EnvironmentObjects folder.
- Introduced HammerThrower class to manage hammer throwing mechanics.
- Updated PlayerController to utilize new InputManager and HammerThrower.
- Refactored PlayerState to manage player state and item collection.
- Enhanced UI management in UiManager to reflect player item collection.
- Updated EnemyAI to remove unused movement logic.
- Adjusted KeyChest to interact with PlayerState instead of Player.
- Cleaned up code and improved event handling for item collection.
