fix(admin): 按任务白名单聚合常规任务金币 (#157)

## 背景

大盘“常规任务金币”原先采用“全部正向金币减排除清单”的反向口径。线上新增 `feed_ad_reward_coupon` / `feed_ad_reward_comparison` 后未同步加入排除清单，导致领券和比价奖励误计入常规任务金币。

## 修改

- 改为明确白名单：`signin`、历史 `signin_boost`、全部 `task_` 任务、`price_report_reward`、`feedback_reward`
- 未知新 `biz_type` 默认不进入常规任务桶
- 增加覆盖领券、比价、广告、邀请、管理员及未知类型的回归测试
- 顺带修复改动文件已有的 Ruff `UP017`

## 验证

- 线上只读 PostgreSQL：新口径全量为 108,022，领券/比价误计差额为 450,675
- Ruff：通过
- `pytest tests/test_admin_read.py tests/test_cps_admin.py -q`：23 passed
