perf(miniprogram): 全面性能优化 — 分包加载 + 请求缓存 + 渲染优化

分包加载（主包从 517KB 降至 275KB，-47%）：
- 将 27 个页面拆入 6 个分包（health/doctor/mall/profile/content/device）
- vendors.js 从 192KB 降至 36KB（-81%）
- echarts 514KB 仅在访问健康趋势页时按需加载

请求层优化：
- GET 请求增加 in-flight 去重 + 60s TTL 响应缓存
- 新建 points store 集中管理积分/签到状态（消除 5 处重复调用）
- health store todaySummary 增加 60s TTL
- mutation 后自动失效缓存（health input/daily-monitoring）
- logout 时清空请求缓存

渲染优化：
- 7 个组件添加 React.memo（EcCanvas/TrendChart/Loading/EmptyState 等）
- 修复 TrendChart setChartReady 导致的双重渲染
- 静态数组（quickServices/quickActions/trendLinks）提取到模块级
- restoreAuth 从页面级提升到 App 级别
- 文章列表图片添加 lazyLoad

构建优化：
- prod 配置添加 terser（drop_console + drop_debugger）
- crypto-js 从全量引入改为按需引入（AES + Utf8）
