feat(monitor): add UserProfile + MonitorMetric catalog + Indicator.seriesKey

数据层(spec 2026-05-26):
- UserProfile @Model:核心 4 项 + 健康背景 + 用药,SwiftData 单例(loadOrCreate)
- Indicator 加 seriesKey: String?,标识长期指标分组('bp.systolic' 等)
- MonitorMetric enum 8 case:血压(2 field 拆 2 Indicator)/ 空腹+餐后血糖 /
  体重 / 体温 / 心率 / SpO2 / 身高
- effectiveRange(for:profile:) 实现 1 条 Profile-aware 规则:
  age >= 65 时 bp.systolic 上限 140→150
- KangkangApp schema 加 UserProfile.self

测试 17 个全绿(UserProfile 6 + MonitorMetric 11);schema 烟测扩 2(seriesKey roundtrip + UserProfile persist)。
UI 层 + Timeline 合并下个 commit。
