feat: 健康录入提醒 + 多指标异常 + 用药漏服 + UI 优化

后端
- NotificationPreference 增加健康录入提醒总开关和 5 子项（血压/心率/血糖/血氧/体重）
- EF 迁移 AddHealthRecordReminder
- 新增 GET/PUT /api/notification-prefs
- 新增 HealthRecordReminderService 每天 9 点/12 点扫描未录入用户推送提醒

前端
- 通知偏好对接真实后端 API
- 设置页新增「健康录入提醒」总开关+5 子项
- 通知中心右上角加齿轮跳设置页
- 今日健康卡片：4 项异常检测+多项合并；用药只显漏服并按时间窗口区分文案
- 侧边栏头像改圆形白底灰图标，去掉紫色品牌渐变
- 整体背景统一浅灰白 #F6F8FC，去掉浅紫渐变
- 设置页简化（去掉分组/彩色图标方块）
- 健康档案保存按钮移到右上角，TextButton 全局默认黑色
- API baseUrl 跟随网络环境
