fix(interaction): 修复编译错误和交互系统集成问题

- SystemDriver: EffectManager改为值持有，去掉TUniquePtr和条件编译
- SystemDriver: 补充EngineUtils.h include修复TActorIterator编译错误
- GameMode: BeginPlay自动Spawn ASystemDriver
- InteractableActor: 改为abstract基类，子类自行创建交互组件
- DoorActor: 创建DoorInteractableComp替代基类组件
- EffectManager: 实现ExecuteToggleDoor调用实际门开关逻辑
- InteractableComponent/DoorComponent: 修复GetGameInstance路径和调用方式
- EffectManager: Broadcast改为Execute（单播委托）
