新增：健康事件时间线接入真实数据（T2-14 时间线半边）

- 时间线页：occurred_at DESC cursor 分页 + 月分组组头，四态齐备；
  六类事件经 RecordTypeDot 映射（增补喂养/洗护/测量三型，色族复用
  已审计色对），类型 TagPill 双通道
- 事件录入表单：六类类型选择器、金额以元录入/整数分传输（money.dart
  换算）、UTC 时间戳约定与体重表单一致
- 事件编辑页：顶层 PATCH 差量提交（title/notes/amountCents + version），
  40902 照 T2-12 模式自动经时间线检索取新 version 重提（保留输入）
- 档案页：月度花费卡接 summary.monthlyExpense（分→元展示）、tz 透传
  设备时区固定偏移（T2-13 遗留③）、健康时间线导航入口
- 埋点：health_record 域 create 三事件 + viewed（recordType=health_event）
  挂通；新增 edit_succeeded/failed 封装（failureReason 含 conflict）
- 测试 224 → 250 全绿（+26）；analyze 0 问题；format 无 diff
