test(mp): service 层测试扩展 — health + consultation + request

新增 3 个测试文件（+23 个测试用例），总计 9 文件 75 测试：
- request.test.ts: HTTP 方法、查询参数构建、缓存、错误处理
- health.test.ts: 体征录入字段映射、日常监测、阈值查找
- consultation.test.ts: 咨询会话/消息 CRUD、已读标记

- 添加 vitest setup.ts mock @tarojs/taro 和 @tarojs/runtime
- vitest.config.ts 增加 setupFiles 配置
