新增：疫苗登记/记录列表与档案页摘要卡接入（T2-13 疫苗半边）

- VaccinationFormPage：目录按宠物物种过滤（四态）、seriesKey 目录 code
  预填、scheduled/completed 状态-日期规则结构化 + 纯函数双重前端拦截，
  42201/40904 后端兜底横幅（均有测试）
- VaccinationRecordsPage：按系列分组、三态 TagPill（含 cancelled 留痕）、
  四态齐备；viewer 隐藏登记入口
- 档案页数据卡行接 GET /pets/{id}/summary 实时聚合：最新体重/疫苗进度/
  下一针三卡，null 语义为空态文案而非 0/0；从记录页返回即重拉摘要
- health_record 埋点装配（app→shell→pets→detail→记录页面族）
- 测试 205 → 224（+19）全绿；analyze 0 问题；format 无 diff
