1. UIToastCanvas.Instance 조회
2. null이면 FindAnyObjectByType<UIToastCanvas>(FindObjectsInactive.Include)
3. 여전히 null이면:
   a. ResolveSettings() → settings.ToastCanvasId 읽기
   b. IsValid 검사 (invalid이면 return)
   c. BundlePool.Spawn<UIToastCanvas>(canvasId)
4. DontDestroyOnLoad(canvas)
5. canvas.isInitialized가 false이면 canvas.Init()

1. Resources.Load<UISettings>(UISettings.ResourcesPath)
2. 없으면 warning 1회 출력
3. service 내부에 cache
4. panel은 GetGroupConfigs()를 통해 전역 group 설정을 조회
5. settings null 또는 empty면 panel 쪽 default group fallback 사용

1. UIToastCanvas.Instance 조회
2. null이면 FindAnyObjectByType<UIToastCanvas>(FindObjectsInactive.Include)
3. canvas가 null이면 → return null
4. canvas.isInitialized && canvas.isInitComplete 모두 true인지 확인
5. canvas.panel이 null이면 → LogWarning, return null
6. return canvas.panel
