feat: [Issue#77] 实现巡检问题上报 + 工单联动功能

- 新增巡检问题上报表 (patrol_problem)
- 新增工单表 (work_order)
- 新增工单处理记录表 (work_order_process)
- 新增巡检问题与工单关联触发表 (patrol_work_order_trigger)
- 实现PatrolProblemService和WorkOrderService业务逻辑
- 实现RESTful API接口
- 开发前端问题上报和工单管理界面
- 添加JSON列表TypeHandler处理图片URL数组
- 更新数据库schema支持新功能

完成了issue要求的：
✅ 巡检中问题上报(类型/描述/拍照)
✅ 自动创建工单
✅ 处理跟踪
