按 UI 五层规范重构 SelectRoleForm 并整理事件目录

- SelectRoleForm 五层归位:UseCase 改为构造注入 IProcedureMenu(新增 Runtime/ProcedureInterface),RawData 暴露原始 StatModifier[] 而非展示串,Controller 复用 ItemDescUtility 拼装属性文本,并修复 OpenUIAsync(object) 合法 RawData 分支缺少 return 的误报路径
- StatModifier 去展示职责:删除 _statTypeNames / ToString,富文本格式化下沉到 Presentation 层的 ItemDescUtility.Describe(StatModifier),CreatePropDescription 改用统一入口
  - 事件目录按 UIForm 归档:Base/Event/UI/Menu/* 拆解到 SelectRoleForm/ MenuForm/ DialogForm/ DisplayItemInfoForm/ Combat/ 等各自子目录,MenuSelectRoleReturnEventArgs 改名 SelectRoleReturnEventArgs,语义归属本 UI 模块
- IUIFormController → IUIController 改名,联动 UIControllerBase / UIRouterComponent / Editor
- 同步更新 docs/UI-5层架构设计规范.md 中相关示例与 MenuForm.prefab、ProcedureMenu 引用
