重构：宠物列表/详情/编辑页接入真实数据（T2-12，四态齐备）

- 档案 Tab 替换为真实宠物列表（05 号规范 P1）：PetsController 四态
  驱动（loading/empty/error+重试/ready），空态插画 + 建档 CTA，
  下拉刷新，虚线添加卡；页面一律走 T2-11 数据层、不直连 ApiClient
- 新增 PetDetailPage（P2 档案信息部分）：内存副本首屏 + getPet 刷新，
  40401 防枚举 → 不存在态返回列表并刷新；仅 owner 显示编辑入口
  （40300 语义）；体重/疫苗/时间线区块留待 T2-13/14 接摘要与记录接口
- 新增 PetFormPage（建档/编辑）：品种目录接口 + 自定义品种互斥
  （目录失败回落自定义 + 重试）、性别契约必填、生日+估算、芯片号；
  失焦+提交双校验、错误三层模型沿用登录纵切
- 40902 版本冲突：明确提示 + 自动拉取最新 version 重提路径（有测试）；
  40903 芯片号冲突字段级报错（有测试）
- 埋点挂接：pet_create_started（表单首次输入、每次进入一次）/
  succeeded / failed 三事件接线；建宠表单路由名 pet_form、详情页
  pet_detail 进入既有 RouteObserver 采集；档案 Tab 页名 pet_archive
  改报 pet_list（字典 v2）；编辑表单不带路由名（漏斗到达段不掺编辑）
- app.dart 装配：pet 服务 ApiClient（:8083）共享 TokenRefresher；
  登出 reset 控制器防跨账号泄漏；PetsController.loadBreeds 按物种缓存
- AppState 清理：pets 页原 demo 消费方移除，vaccines 及其模型/持久化
  删除；pet demo 仅存首页问候/创作页/主壳头像（后续工单收敛）
- 头像按 ADR-010 本地占位，不做上传
- 测试 145 → 177 全绿（列表/详情/表单四态与冲突路径 widget 测试、
  控制器 loadBreeds/reset、展示纯函数）；analyze 0；format 无 diff
