perf(log): optimize PG log store queries and expired partition cleanup
- Count/节点访问日志统计改为单次扫描聚合,WAF 按 IP 聚合由三次扫描合并为两次 - IPSummaries 归属地改为取过滤窗口内最新记录(对齐 ClickHouse argMax 口径), 子查询带窗口条件,可分区裁剪并命中索引 - 新增 goose 迁移:of_node_access_logs (logged_at DESC, id DESC) 前导索引与 lower(trim(host)) 表达式索引,加速列表排序与主机过滤 - 过期日志清理先按数据校验直接 DROP 完全过期整月分区,再对边界月逐行删除; 启动时兜底预建当月及未来 2 个月分区,跨月停机重启后首次写入不再报 "no partition of relation found"
