fix: 心维度页面 loadHealthAlerts/loadMilestones 移除残留 familyId 存储读取（后端已 JWT 派生）

loadHealthAlerts 调用 getHealthAlerts()（api.js 签名本就无参，familyId 入参被忽略）；loadMilestones 改为 getMilestones(30) 修正 daysAhead 误传 familyId 的预存 bug。两个方法此前仍读取已废弃的 currentFamilyId storage + userInfo.familyId 兜底作为 guard，但后端 familyId 现由 @RequestAttribute 注入，guard 与 storage 读取均为死代码。
