协议：按0824协议更新复合管控通信解析 + 新增燃料电池监控网页

- pmSysvariable/ccuUdpMsg: 域起始符改为0x40 0x40，域标识符重编号0x0001~0x0004，
  ccuState/ccuColCmd/ccuSetParmCmd 按新协议字段布局与字节序重写（状态248B/操控45B/参数28B）
- systemData/httpserver: 新增FC单片电压、甲醇制氢装置、DC/DC、尾气装置、一体化罐、
  供氢供氧流量、应急上浮等字段解析与WebSocket JSON推送
- 新增 /fcs 燃料电池监控页（fuelcell.h）：实时数据显示 + 操控指令交互按钮，
  过滤日志推送消息避免界面闪烁
- SQLite/LowerCommManager/测试：更新建表列、解析打印与单元/集成测试适配新协议
