refactor(profile,monitor): move height/weight from MonitorMetric to UserProfile

身高/体重对成人变化慢,作为 Profile 静态字段比每次录入 Indicator 更合适。

- MonitorMetric:6 case(从 8 减),删 .height / .weight
- UserProfile:加 weightKG: Double?(支持小数),加 bmi computed
- summaryLine 加体重段:'175cm · 68.5kg'(整数省小数)
- ProfileEditView basics 加 weight 行 + footer 显示 BMI + 分类(偏瘦/正常/超重/肥胖)
- IndicatorQuickSheet:删 .height 回写 Profile 的特殊逻辑
- UserProfileTests:+5 个(weight 字段、summaryLine 含 weight、BMI 计算)

兼容性:老 Indicator 里的 seriesKey 'weight' / 'height' 数据保留(SwiftData String?
不变),只是新录入路径走 Profile 不走 Indicator;Trends 仍能用 String seriesKey
查询历史(如果将来要展示老数据)。

测试:60 case pass / 0 fail / 0 warning。
