新增：照护提醒接入与疫苗流转收尾（T2-14 提醒半边 + T2-13 遗留）

- 照护提醒页：status 过滤（服务端白名单视图）、due_at ASC、逾期红标
  双通道标识，四态齐备；创建表单（四类）+ 完成（completedAt 必带、
  支持补记）/ 忽略（禁带 completedAt）流转，42202/40902 兜底重拉
- 档案页：「健康提醒」卡改真实待办数据驱动（取代 demo 硬编码文案，
  最近到期一条 + 逾期警示形态），照护提醒导航入口带待办数副行
- 疫苗列表（25 号报告遗留①②）：scheduled 行「标记完成/取消登记」
  PATCH 流转；完成对话框补录厂商/批号（契约可选字段）；
  42201/40902/40402 兜底
- 埋点：create 三事件 + viewed（recordType=reminder）挂通；
  edit_succeeded/failed 挂 vaccine 流转（failureReason 含 conflict）；
  提醒完成/忽略按 06 §7 缺口 3 既定取舍不埋
- 测试 250 → 272 全绿（+22，较基线 +48）；analyze 0 问题；format 无 diff
