refactor(mobile): 移动端 11 页改用移动组件，消除桌面件混用

问题
- 移动端大量误用桌面组件（ui-avatar / ui-button / ui-modal / ui-select），
  按桌面密度设计（40px 头像、8px 圆角），在移动端视觉偏小、比例失衡

组件映射
- ui-avatar      → app-m-avatar（自建，移动 44px；底座无 ui-m-avatar）
- ui-button      → ui-m-button（outline 无此变体，改 secondary）
- ui-modal       → ui-m-dialog
- ui-select      → ui-m-dropdown-menu
- ui-empty/skeleton/tag/segmented/tabs → 对应 ui-m-*

外壳与首页
- 移动外壳：手写 TabBar → 底座 ui-m-tabbar；Tab 索引改由 Router 事件流推导
  （替代 setInterval 轮询 location）
- 移动首页：ui-m-section-header / ui-m-cell / ui-m-cell-group / ui-m-notice-bar

验证
- 移动端零桌面组件标签；16 种 ui-m-* + app-m-avatar
- 8 页实机截图：无横向溢出、无桌面件、无控制台错误；TabBar 激活态逐页正确
- verify:ui 11/11（含修复本次引入的 2 项回归：裸断点、覆盖块超预算）
- 构建 451KB（gzip 114KB）；289 单测；ui-kit 覆盖率 35 个组件

+| **git 推送** | 提交 `362a011`（1710 文件）→ 推送至 `https://git.fmode.cn/ice-static/fmode-app.git` 的 `master` ✅ |
+| **用户要求** | 「不要出现 mobile 端却有 PC 端组件样式」——按移动端规范重做,并复用桌面端已确立的规范 |
+| **发现的问题** | 移动端 11 页大量混用**桌面组件**:`ui-avatar` / `ui-button` / `ui-modal` / `ui-select`(桌面尺寸与密度,在移动端视觉偏小、比例失衡) |

- * 🔴 AC-19.1 **计数与列表条数一致**（修正存量「显示 20 却只有 6 行」的误导）
- * 🔴 AC-19.2 **每个区块独立三态**，错误态**不得伪装成「暂无交付成果」**
- * 🔴 AC-19.3 输入/字号 ≥16px（由全局与组件保证）
- * 🔴 AC-19.4 「全部」分别落到 /mobile/events、/mobile/deliverables、/mobile/messages
+ * 实现纪律（用户要求：**不要出现 mobile 端却有 PC 端组件样式**）：
+ *   · 区块标题用 `ui-m-section-header`（移动件,非桌面风格）
+ *   · 列表行用 `ui-m-cell`（移动列表标准件）
+ *   · 空/加载用 `ui-m-empty` / `ui-m-skeleton`（移动件）
+ *   · 头像用 `app-m-avatar`（移动尺寸 44px；底座无 ui-m-avatar）
+ *   · 触达区 ≥44px、安全区由外壳处理
