fix(plugins): 插件管理 - 修正官方应用插件的分类与状态显示

AI 审美分析和剪辑工作台在管理页显示为"已停用"，原因是三处插件
分类清单不一致：

- 后端 officialApplicationPolicies 缺少 editor-shell
- 管理页 officialApplicationIds 同时缺少 ai-art-critique 和 editor-shell
- 用户插件页另有一份重复清单

后端把这两个插件当作系统协议处理（Kind=protocol），platformAvailable
回退为 false，于是返回"管理员已停用该插件"，管理页据此渲染成"已停用"。

修复：

- 后端补上 editor-shell 应用策略（权威修复，决定平台可用性）
- 前端抽取唯一清单 OFFICIAL_APPLICATION_PLUGIN_IDS，管理页与用户插件页
  共用，删除两份重复实现
- 补前后端回归测试，锁定这 8 个官方应用插件

验证：tsc --noEmit 通过；前端 17 项测试通过；后端 TestEditorShell* 与
既有插件测试通过；前后端镜像构建通过。
