"""日志查询 API（凭 log API key 鉴权）：/api/logs/*

用途：不依赖 admin key，凭可吊销的随机 API key 查询请求日志，
方便外部工具/脚本排查线上问题（key 由 /admin/api/log-keys 生成）。

鉴权方式（二选一）：
- 请求头 X-XTC-Log-Key: <key>（推荐，避免 key 进代理/访问日志）
- query 参数 ?key=<key>

注意：/api/logs 不在 request_log 中间件的记录范围内（只记录 /v1/ /admin/api/ /u/api/），
查询行为本身不会被记录，避免 key 泄露到日志存储。
