* Nginx 访问日志聚合统计 Service（Base 内核）.

|

* 设计要点：
|
||
* - 幂等：delete-then-insert 模式（不用 INSERT ON DUPLICATE KEY UPDATE，避免翻倍）
|
||
* - 事务：Db::startTrans / commit / rollback 包裹所有 DELETE + INSERT
|
||
* - top N 截断后不保留长尾（明确接受，不在 sysconfig 控制"是否截断"）
|
||
* - 依赖倒置：内部 use app 入口 model（NginxStatHour 等），不 use Base model
|
||
* - 只读 raw 表（ul_nginx_access_log），不做 nginx log line 解析（那是 T5 Parser 的事）
