refactor(quality): Q23 前端巨型组件拆分 — CloudAccountManager 572L→308L (-46%), 提取 cloud-account/ 3 个文件 (types(AccountFormData/AccountStats/ActionLoading + 6 个纯函数 helper) + AccountCard(178L 受控展示组件) + AccountFormDialog(162L 创建/编辑表单 Dialog)), catch 类型安全升级 (e?.message→e instanceof Error), 零逻辑变更, ESLint errors=0/warnings=0/any=0, tsc -b=0, npm build✓ (17.14s), 17/17 测试通过
