fix(miniprogram): 首页体征数据加载时序 + 并发控制 + 权限修复

- ConcurrencyLimiter 12→8 预留长轮询通道，避免超微信 10 并发限制
- usePageData 添加 AbortController，页面隐藏/卸载自动取消请求
- useHomeData 添加 useEffect 监听 currentPatient 变化自动触发数据加载
- 医护人员首页跳转前不渲染 HomeDashboard，避免触发无用 API 请求
- auth.ts getPatients 正确提取分页响应 .data 数组
- health.ts getTodaySummary 从 Storage 回退读取 patient_id
- health store refreshToday 从 auth store 回退获取 currentPatient.id
- auth store restore() 状态变化时清理请求缓存，避免返回过期数据
