Extend VContainer DI: eliminate manual composition and duplicate references

- Register InventoryModel, ShopModel as container-managed singletons
- Register GameController, ShopController, InventoryController via RegisterComponent
- Replace [SerializeField] with [Inject] for service dependencies in controllers
- Move maxActiveModifierSlots config to GameLifetimeScope (composition root)
- Remove manual model creation and Initialize() calls from GameController
- Add ToggleVisibility() to ShopController/InventoryController, removing GetComponentInChildren
- Move event subscriptions from Awake to Start for safe VContainer injection order
- Transfer game startup orchestration to GameController.Start()
