feat(uart): 分离ETH与Cat1通讯，支持UART1/Cat1/Debug互斥切换

Breaking Changes:
- USART1(PA11/PA12)改为Cat1(115200)/Debug(500000)共享，SGM3157控制
- USART4(PB09/PC13)独家给ETH(115200)，不再共享
- 新增EthTask独立状态机，与CatOneTask解耦运行
- 上电默认Comm=CATONE_COMM，dch=RS485_CH1

Details:
- feat: 新增EthTask.c/h，ETH状态机(8态)独立运行
- refactor: CatOneTask移除ETH代码，AT发送/接收走USART1
- feat: comm cat1/eth命令增加USART1占用互斥检查
- feat: dch dbg命令增加USART1占用互斥检查
- feat: rt_kprintf根据dch通道自动路由(USART1/RS485)
- feat: 新增eth on/off调试打印开关命令
- fix: 两个状态机按Comm模式判断休眠，避免误发AT
- fix: bsp.c修复IRQ回调函数名不匹配(BusFault隐患)
- fix: PB08(PortB Pin08)PORT_Init触发复位，改用外部上拉+POUTE单bit使能
- fix: DebugCmd命令表DEBUG_CMD_CNT与实际条目数不符(crash风险)
- chore: 删除InfTest死函数、重复include、无用宏声明、EthRev_Sem等冗余代码
- chore: 更正中文标点(！→! ，→,)
