feat(admin): 领券点位分数支持查看明细 (#56)

## 变更内容
- 领券记录列表的点位成功率展示为成功数/尝试数，例如 8/8
- 点击分数弹出点位明细
- 逐条展示点位名称、ID、成功、已领、失败或跳过状态
- 失败点位额外展示失败原因
- 无逐券埋点的旧记录显示 -

## 依赖
- 依赖 app-server #153 提供 point_success_count、point_total_count 和 point_details

## 验证
- npx tsc --noEmit
- npm run build
- 本地实际验证 8/8 全部成功和 7/8 含失败原因两种状态
