fix: 修复放电功能相关的若干问题

Browse Source 
1. 修改apps/chrg/applications/utils/chrg_sink.c：
   - 调整寄存器数组长度，新增继电器控制相关的初始化配置
   - 在放电初始化前先关闭所有功率板继电器
2. 修改apps/chrg/applications/thread/chrg_north.c：
   - 修复变量类型不匹配问题，将uint8_t改为rt_uint8_t
   - 新增参数合法性校验逻辑，避免空指针和越界访问
   - 新增电压状态标记，仅在电压有效后才将低压视为故障
   - 修复无符号整数溢出问题，避免电压差值计算异常
   - 优化电流异常时的状态机切换逻辑
   - 非工作状态下重置所有状态标记
