fix: 联合调试问题修复 — 预约错误提示 + request 错误提取 + copilot 解包

- ISSUE-APPOINTMENT-001: 后端 DoctorNotFound 改为 Validation 错误（400）
  + 改善错误消息"所选医生暂无医护档案，请联系管理员"
  + 小程序预约创建 catch 传递实际错误消息（不再硬编码"预约失败"）
  + 小程序 request.ts 提取后端 message 字段作为用户提示
- copilot API: listInsights/listRules/getPatientRisk 补齐 data.data 解包
- 移除 error.rs 重复的 AppointmentNotFound 分支
