pCCU新增锂电池通信/协调操作 + 电源协调状态机骨架(惰性)

锂电池通信(docs/锂电池协议20230324.docx)：
- 协议层 BatProtocol：自检0x0000(2B)/设备控制0x0001(17B)/电池组状态0x0003(80B)/
  电池包报警0x0004(68B)，uint32字节和校验、小端
- 链路层 BatLinkManager：动力/仪表锂电池独立UDP链路，本机监听与远端IP端口
  均由.moos配置(dyn_bat_*/ins_bat_*/bat_work_condition)
- SystemData/SnapshotBuilder/网页：电池数据按动力/仪表归类展示(运行状态/接触器
  电气量/电池包电压温度/报警)，收发帧落库SQLite，网页新增电池标签页

操作->指令下发(PowerCoordinator)：
- 操作接口：自检/上下电(母线接触器55H接通77H断开,含预充)/功率设定(0~500kW)/
  电池切换(低压->高压6步、高压->低压5步,按协议时序)
- 步骤引擎：每电池独立步骤队列，下发->状态反馈确认->超时兜底；周期1s心跳控制帧
- PM操控指令insBatCmd/dynBatCmd/dynBatPower自动映射为电池操作

电源协调状态机骨架(CoordFsm, TinyFSM)：
- 事件Tick/PmControl/StepDone + 状态Normal/Switching/Fault，react均为TODO占位
- 当前未接线(无start/dispatch调用,运行行为与接入前一致)，CoordFsm.hpp头部附接线指南

测试与部署：
- pccuTest新增电池协议编解码/帧长/链路分发用例(175项通过)；集成测试覆盖电池
  心跳、启停映射(0x10->0x55/0x20->0x77)、状态落库；同步pccu_it.moos与ws_check
- h100.moos与pCCU.moos增加锂电池链路配置；归档锂电池协议文档
