fix: QA 全量测试发现 5 个 bug 修复

- [P0] 登录失败无反馈: client.ts 响应拦截器跳过 /auth/login 的 401 处理，让错误传播到 Login 组件
- [P0] 统计仪表盘 400: 前端用独立 try/catch 替代 Promise.all 提高容错性；后端 stats_service 白名单补充 ultrafiltration_volume/dialysis_duration
- [P1] 随访负责人显示 UUID: 批量解析 assigned_to 用户名
- [P2] 消息中心时间未格式化: 添加 formatDateTime 函数
- [P2] 首页显示 login_failed: 过滤审计日志中的 login_failed 动作
