feat(ops): 新增轨迹统计接口 summary/hourly-trend/area-stay-stats

- summary: KPI 卡片（作业时长、覆盖区域数、事件数、平均停留）
- hourly-trend: 按小时聚合出入趋势
- area-stay-stats: 区域停留分布（含 fullAreaName，按时长降序）
- deviceId 可选，不传则汇总全部设备
- selectByDateAndDevice 加 LIMIT 5000 安全上限
- 删除无调用方的 selectTimeline 方法
- enrichWithAreaInfo 改用 buildPaths 批量构建路径
