feat(wm-production): #10 修复 VideoMonitorController 编译错误 + 补齐 AI闯入检测(MON-07~09)

wm-production 模块 90% 实现已在 master（Dashboard/Gis/Monitor/Video 等），唯一阻塞点是 VideoMonitorController 编译失败：它调用 IntrusionDetectionService 的 10 个方法，但 Service 仅有 4 个且基于错误假设的实体字段（eventNo/detectedTime/confirmedBy/status(String) 等，IntrusionEvent 实体均无），导致整个 wm-production 模块编译失败。

本次重写 IntrusionDetectionService，对齐 IntrusionEvent 真实字段（cameraId/alertStatus/detectedAt/handleResult/handledBy 等），实现 VideoMonitorController 调用的全部 10 个方法：

- detectIntrusion(cameraId, frameData): 单路 AI 检测，命中生成事件
- batchDetect(cameraIds): 批量多路检测
- pageEvents(8维筛选): 分页查询闯入事件(按摄像头/区域/等级/状态/时间)
- getEventById / confirmEvent / handleEvent / dismissEvent: 事件详情与状态流转(待处理→已确认→已处理/已忽略)
- getIntrusionStats(period): 按 today/week/month 统计(总数/各状态/平均置信度/误报率)
- getIntrusionTrend(days): 按天趋势
- getTopIntrusionCameras(limit): 高频闯入摄像头排行

补充 IntrusionDetectionServiceTest（覆盖检测/查询/处理/统计/排行，15 用例）。
对齐 IntrusionEvent 真实字段，零编译风险（无 eventNo/detectedTime/confirmedBy 等不存在字段的调用）。符合设计文档 5.3。
