+-- 自录业绩/账户消耗：把唯一索引补上 delete_time，使软删后可重新录入。
+--
+-- 背景：
+--   旧索引 uk_creator_date_media = (creator_id, date, media_source) 不含 delete_time，
+--   软删的历史记录会继续占用唯一键，导致同账号同日同渠道再次新增触发 MySQL 1062。
+--
+-- 新索引 uk_creator_date_media = (creator_id, date, media_source, delete_time)
+--   MySQL 中 NULL ≠ NULL：
+--     - 活跃记录 delete_time = NULL，最多 1 条（行为不变，仍唯一）
+--     - 软删后 delete_time 变成时间戳，与新插入的 NULL 不冲突 → 允许重新录入
+--
+-- 可重复执行：先检查再操作，避免 1091/1061 报错。
