test(web+mp): E2E 测试全量实施 — Web 5 flow + MP 4 flow + 基础设施

Web 端 (Playwright):
- fixtures: test-data 工厂 + API Client (乐观锁 version) + 增强 auth fixture
- pages: LoginPage, PatientListPage, PatientDetailPage, HealthDataPage, AppointmentPage
- flows: 患者全流程, 体征数据链路, 预约排班链路, 随访管理链路, 告警处理链路
- smoke tests 迁移到 smoke/ 目录，import 路径更新
- playwright.config.ts 更新: globalSetup 环境检查, 60s timeout, video retain

小程序端 (Vitest + miniprogram-automator):
- helpers: AutomatorClient, MpApiClient, MpAuthHelper, MpNavigator
- flows: 患者健康数据查看, 体征数据录入, 积分签到兑换, 积分商城浏览
- vitest.config.ts + check-readiness.ts
- vitest 4.1.5 依赖安装

Playwright 发现 15 个测试 (5 flow + 10 smoke)，全部就绪
