feat(desktop): 稳定桌面端界面与文件操作反馈

- 重构 DesktopPreferences 为分栏式设置面板，整合连接、外观、通知、更新与诊断信息分区，并补充过渡动效与暗色主题样式
- DesktopLayout 侧边栏导航分组支持展开折叠，调整管理/项目区块顺序并统一图标与标题
- 新增 fileTaskFeedback 工具，统一 pickFiles/saveFile/openFile 的成功/取消提示，替换审计导出、权限日志、附件、文档、线程、项目配置等处的直接调用
- desktopUpdateManager 暴露更新状态快照与状态变更监听，区分检查中、安装中、已推迟、失败等状态
- DesktopServerSettings 增加连接诊断信息（检查时间、健康地址、耗时、HTTP 状态）
- unified-page.css 与 ProjectMilestones 引入 CSS 变量以适配暗色主题
- WebLayout 将服务器设置入口改为打开系统偏好面板，管理菜单中邮件服务归入系统设置分组
- ProfileSettings 移除已迁入偏好面板的桌面端专属区块
- 补充 Layout.desktop 布局与偏好面板契约测试

+处理 CTMS 桌面端任务前，必须先阅读 `docs/desktop-project-plan.md`。桌面端任务包括但不限于 Tauri、macOS、Windows、桌面打包、桌面存储、文件集成、系统通知和桌面端安全边界。
 
-桌面端当前不是空白初始化项目。Tauri 基线、macOS 在线桌面壳和第二阶段原生能力主体已经形成；后续工作限于修复、稳定化、体验收口、发布准备、在线辅助缓存、Windows 兼容验证和已批准的 Windows 正式发布。不得重新按第一阶段空白项目初始化 Tauri，不得绕过现有 `frontend/src/runtime/` 适配层直接在业务模块中使用 Tauri API。

-除非用户明确要求先调整本文件中的约束，否则不要实现离线功能、本地业务权威数据存储、内嵌后端服务、离线同步、本地优先工作流或新的阶段性桌面产品线。在线辅助本地缓存只允许作为已认证在线客户端的体验加速能力；处理桌面本地缓存、请求去重、条件请求、缓存诊断或缓存清理相关任务时，必须阅读并遵守 `docs/desktop-local-cache-plan.md`。
+`docs/desktop-project-plan.md` 是当前桌面端进展和工作边界的事实来源。本文件只保留执行约束，不重复维护审查结论或优化方向；不得重新按第一阶段空白项目初始化 Tauri，也不得绕过现有 `frontend/src/runtime/` 适配层直接在业务模块中使用 Tauri API。如实际代码状态与计划书不一致，先更新计划书再实现。
 
 处理前端或桌面端实现时，优先保持以下边界：
 
 - 共享业务代码通过 `frontend/src/runtime/index.ts` 获取平台能力。
 - Tauri API 仅允许出现在 `frontend/src/runtime/`、`frontend/src-tauri/` 或有明确记录的窄入口中。
-- 本地缓存能力只能通过 `frontend/src/runtime/desktopDataCache.ts`、`frontend/src/runtime/index.ts`、`clientRuntime.dataCache` 和 API 客户端的受控入口暴露；业务模块不得直接使用 Tauri 存储 API、文件系统、SQLite、IndexedDB 或 Cache Storage 实现缓存。
-- 未完成后端 token 校验和 `/me` 身份确认前，不得展示业务缓存；登出、切换服务器、切换用户、401/403、权限上下文变化或缓存 schema 变化时必须清理或失效相关缓存。
-- 新增或调整 Tauri command、capability、CSP、updater、凭据、文件、通知、本地缓存持久化或底层存储能力时，必须同步评估 `frontend/scripts/verify-desktop-release.mjs`、`npm run runtime:check` 和桌面发布检查清单是否需要更新。
+- 新增或调整 Tauri command、capability、CSP、updater、凭据、文件、通知能力时，必须同步评估 `frontend/scripts/verify-desktop-release.mjs`、`npm run runtime:check` 和桌面发布检查清单是否需要更新。
 - token、附件下载凭据和敏感业务信息不得写入 URL、日志、系统通知正文或明文浏览器存储。
-- 正式桌面客户端的默认 CTMS 服务端入口必须由构建环境变量 `VITE_DESKTOP_SERVER_URL` 注入，不得在运行时代码中写死生产域名；用户仍可在桌面服务器设置中手动覆盖，手动值优先并沿用既有的切换服务器登出与缓存失效边界。该变量只表示业务服务端 origin，不得与 updater 制品前缀 `DESKTOP_UPDATE_BASE_URL` 混用。
-- Windows x64 NSIS 已获准作为正式桌面发布目标；正式制品必须由 `.github/workflows/desktop-release-candidate.yml` 从与 macOS/Web 相同的 `vX.Y.Z` tag 和 SHA 构建。平台签名默认要求组织 Windows 代码签名证书、RFC 3161 时间戳和 Authenticode 校验；只有 `frontend/desktop-release-policy.json` 中按精确版本记录、经发布负责人批准的例外可跳过平台签名。无论是否采用平台签名例外，都必须使用 updater 私钥、校验 updater feed，并明确标记平台未签名风险。`.github/workflows/desktop-windows-internal.yml` 仍只用于分支上的无签名兼容性验证，不得生成生产 `latest.json`、updater feed 或正式发布制品。
-- v0.1.0 另获准在 GitHub Actions 额度不可用时，从最终 `release` 上不可移动的 `v0.1.0` tag/SHA 在受控 macOS 主机本地构建并先行上传 macOS ad-hoc 制品；Windows 只能在额度恢复后从同一 tag/SHA 后补。面向安装用户的 GitHub Release 只保留 DMG 与只校验该安装包的 `SHA256SUMS.txt`，平台未签名风险和 Windows pending 状态写入 Release Notes。macOS updater 包及 `.sig`、完整 checksum、provenance、`UNSIGNED-PLATFORM` 与 Windows pending 证据必须保存在被 Git 忽略的私有发布目录，待 Windows `NotSigned` 制品和联合 feed 均验证通过后再发布到可匿名读取的独立 HTTPS updater 源；此前不得发布或替换生产 `latest.json`。该本地/分阶段例外不适用于后续版本。

-正式桌面发布构建必须使用组织批准的 updater 签名私钥，updater 签名不可因平台签名例外而关闭。平台签名默认要求 macOS 完成 Apple 签名/公证、Windows 完成组织代码签名、RFC 3161 时间戳和 Authenticode 校验。当前仅批准 v0.1.0 采用受控分发例外：macOS 使用 ad-hoc 签名且不公证，Windows 应用和安装器保持 Authenticode 未签名；制品名、Release Notes、私有发布证据、完整 updater 校验清单和 provenance 必须清楚标注 `UNSIGNED-PLATFORM`，并提示 Gatekeeper/SmartScreen 警告。面向安装用户的 GitHub Release 可按精确版本策略精简为安装包与对应 checksum，但不得因此删除私有 updater 签名制品或验证证据。该例外不自动适用于后续版本。
