feat(admin-web): AIPrewarm 分组展示 + 每行触发 + AppType 联合类型

1. AIPrewarm.tsx:
   - areaToAppType(area) helper · area='all' → app2_finance · 其他 → app2a_finance_area
   - handleRunOne / handleBackfillMissing 按 area 动态选 app_type
   - MissingRowWithGroup 含 __group_header 字段
   - groupedMissing 数据构造（全域 + 区域两组 · 每组前插 header 行）
   - 每列 onCell colSpan 合并单元格实现"全域 / 区域"分组标题行
   - Descriptions 加全域 8/X + 区域 64/X 双段统计

2. api/adminAI.ts:
   - 新增 AppType 联合类型（9 项，含 app2a_finance_area）
   - runApp 签名 appType: AppType（替代原 string）
   - RunAppResponse.app_type 同步为 AppType

3. AIOperations.tsx:
   - runAppType state 类型改为 AppType | undefined
   - import { AppType } type

实测：
- pnpm tsc --noEmit 全项目通过
- playwright E2E 访问 /ai/prewarm 显示 "全域 8/8 · 区域 63/64" 分段统计
  分组标题行正确合并 · 单独生成按钮按 area 路由到正确 app_type
