cbb a7a3805839 feat(ADC): 电流采样支持负数
将 CURRENT_OFFSET 从 0 修改为 -1.60f 以校准电流采样偏差。
同时将 ADC 规则通道的采样时间从 55.5 周期调整为 28.5 周期,提高采样响应速度。

feat(timer): 新增 TIMER1 中断及 PWM 周期位置触发功能
新增 TIMER1_CH3 用于在 PWM 周期特定位置(如 50%)触发中断,并配置相关 NVIC 和中断处理逻辑。
修改 TIMER3 的定时周期注释与实际值一致,为 50 微秒。
重新组织 TIMER2 中断中的任务调度顺序,提升执行效率和逻辑清晰度。

refactor(main): 重构主循环任务处理顺序
调整 main.cpp 中任务执行顺序,确保高优先级任务及时处理。
将部分传感器更新任务移动至更合理的位置,保证数据同步性和控制实时性。
