feat(钢卷跟踪): 从哪开始获取计划?一次性获取多少个计划?不同批次的顺序号相同怎么处理?

已实现的功能:
Systemcount+信号变化才算有效
状态机逻辑：信号1必须配合计数器变化才触发，然后等待信号2
信号2必须配合计数器变化+保持2秒才触发
第一批1-5，第二批2-6，第三批3-7
每次取5个钢卷，顺序号滑动+1
信号2触发时更新Oracle追踪表
OPC页面配置点位
信号1(入口钢卷)节点配置
信号2(焊接完成)节点配置
计数器节点配置
保存后自动重启OPC服务
前端操作中间表 ✅
TrackCoil页面可增删改查临时表
可手动调整顺序
模拟信号1/信号2按钮可测试

- 后端新增钢卷跟踪相关API和数据库表
- 前端添加钢卷跟踪管理页面
- OPC服务增加信号节点监控和状态机处理
- 实现钢卷跟踪的自动更新逻辑
