fix(backend): 档位种子对齐迁移431新档位 + 清理旧档残留

迁移418 seedCfSalesTiers 每次启动按缺行才补插入旧档种子(青铜100/白银500/黄金2000/铂金5000/钻石10000)，
而迁移431 已将 min 改为 10000/50000/200000/500000/1000000，导致旧档(如5000,55%)被重新插入为6-9行，
与1-5新档(新秀/小成/...至富)并存。CfReferralService 按 min DESC 匹配时，旧档抢在新档前，
如 P点=7000 命中旧铂金(5000,55%)而非新秀(10000,10%)，销售奖费率超标。

- CF_DIRECT/INDIRECT_SALES_TIER_SEEDS 更新为新档(新秀10000/小成50000/中富200000/大成500000/至富1000000)
- seedCfSalesTiers 前置清理：删除 min 不在新档阈值集合内的旧档行(幂等)
