新增：档案页共享组件三件 + TagPill 深变体映射（DEBT-1 偿还）

- PetAvatar 四尺寸档（96/64/44/32）收敛头像重复实现：3px 白描边 +
  轻投影，编辑徽标底改 primaryStrong（白图标 4.49:1 达非文字 3:1），
  M2 无上传（ADR-010），url 缺省渲染本地占位形态
- RecordTypeDot 三尺寸档 + 五类记录类型的图标/三色映射唯一出口
  （05 号规范 §2 表，供 T2-13/14 时间线复用）
- EmptyStateIllustration 空态插画区（112 圆 + 标题 + 说明 + 可选 CTA）
- TagPill 增可选 inkColor，缺省按 color 查深变体映射
  （primary→primaryDark 8.74:1 / success→successInk 7.39:1 /
  accent→accentDark 7.07:1 / error→errorDark 5.78:1 / 未命中→ink），
  既有调用零参数回归
- AppColors 新增 errorDark #B02C25、inkSoft #6B5A4A（05 号规范 D8）
