refactor(mp): 架构重构 — usePageData 统一数据加载 + Store 解耦 + 大页面拆分

新增 usePageData hook（useDidShow 节流 + usePullDownRefresh + loadingRef 防重入 + enabled 条件守卫），
44/58 页面迁移接入，消灭 4 种数据加载模式并存。

- 新增 hooks/usePageData.ts — 统一页面数据加载生命周期
- 新增 stores/index.ts — resetAllStores() 解耦 auth↔health store 依赖
- 新增 pages/index/useHomeData.ts — 首页数据 hook（424→282 行）
- 新增 pages/health/useHealthData.ts — 健康页数据 hook（422→254 行）
- 44 个页面迁移到 usePageData（9 患者端 + 15 医生端 + 20 子包）
- auth store logout 不再直接导入 health store

构建通过，测试 74/75（1 个预存失败）。
