fix(dashboard): 比价/领券奖励金币按 feed_scene 汇总(修复恒 0 + 激励视频双计)

比价/领券奖励金币此前查 coin_transaction.biz_type in (comparison/coupon...),
但这些 biz_type 全站从未写入——比价/领券信息流广告金币实际记为 feed_ad_reward、
场景区分在 ad_feed_reward_record.feed_scene——故两卡恒 0;领券桶还误含
reward_video/ad_reward,把激励视频金币双计进领券。

改为:comparison/coupon 奖励金币 = biz_type 桶(历史空、留作兜底)+ 按
ad_feed_reward_record.feed_scene 的 granted 实发金币(reward_date 北京自然日窗口);
reward_video/ad_reward 拆成独立 REWARD_VIDEO_BIZ_TYPES,不再混入领券,
REGULAR_TASK_EXCLUDED_BIZ_TYPES 保持不变。

测试:tests/test_admin_read.py 加 3 个用例(比价/领券按 feed_scene 汇总、
too_short 不计、领券排除激励视频);全量 pytest 除 5 个既有失败外全绿。
