fix(web+health): E2E flow 测试全面修复 — 15/15 通过

- test-data: 接口对齐后端 DTO（VitalSigns/AlertRule/Schedule/FollowUp）
- api-client: 增强 HTTP 错误处理（parseJson 统一防护非 JSON 响应）
- auth.fixture: 每个测试获取新 token，避免共享 token 过期
- patient-detail: tab 名称修正为 '健康数据' → '体征数据'
- patient-list: DrawerForm 选择器适配（无 phone 字段、保存按钮在 extra）
- vital-signs-flow: API 录入 + 页面验证，避免复杂 DatePicker 交互
- alert-flow: 简化为规则 CRUD + 页面导航，condition_params 对齐后端格式
- follow-up-template handler: 权限码从 health.follow-up-template.* 修正为 health.follow-up.*
- playwright.config: workers=1 串行执行避免并发登录
- check-readiness: 健康端点路径修正为 /api/v1/health
