重构：统一 UI 模块目录结构规范

- 事件命名规范化：RefreshEventArgs → LevelUpRefreshEventArgs
- LevelUp 子组件目录调整：LevelUpRewardItem + LevelUpRewardItemContext 移动到 LevelUp/
- Shop 子组件目录调整：DisplayItem/DisplayListArea/GoodsItem/ShopGoodsItem 及其 Context/RawData 全部移动到 Shop/
- 删除冗余文件：LevelUpRewardItemRawData（从未被使用）
- 新增 ObjectPool 目录结构
- 更新 LevelUpController 和 LevelUpForm 中的事件引用
