// 配额模式 repo 层集成测试：
//   - Create/GetByID/Update 的 check_mode/account_id 往返
//   - InsertHistoryBatch → ListHistory / ListLatestForMonitorIDs 的 quota JSONB 回读
//     （裸 SQL 列 + scanMonitorQuota），以及探活模式旧行 quota=NULL 的兼容
//
// 注意 channelMonitorRepository 的 GetByID/裸 SQL 走全局 client（不识别 tx ctx），
// 因此本文件用 integrationEntClient 直连 + t.Cleanup 显式清理，不走 testEntTx 回滚。
