fix(gateway): 修复 local finalize 与 usage 聚合相关测试失败

- 修正内存 usage 仓库的时间单位处理，恢复 stats/monitoring/dashboard/wallet/pool 聚合结果
- 允许 openai:compact 走 CLI 响应转换与本地 finalize cross-format 路径
- 更新 cross-format 测试夹具，显式启用 enable_format_conversion
- 调整 failover 测试优先级，消除候选平局导致的顺序不稳定
- 补齐 ai_pipeline 架构断言所需导入并清理残留 runtime 空目录
