1、设备上电红灯红灯常亮
2、设备连接上COM口红灯闪烁
3、设备连接上BLE绿灯常亮
4、设备进入OTA绿灯闪烁

/******************************************************************************
* @file usr_led_status.c
* @brief 状态指示灯实现
* @author cyWu <1917507415@qq.com>
* @date 2026.08.03
* @version V1.0.0
* @history
* - V1.0.0, 2026.08.03, cyWu, 首次发布
*
* 显示规则：
* 红灯(PA8)：上电常亮；COM(DTR)打开时 1Hz 闪烁（优先于常亮）
* 绿灯(PA7)：BLE 已连接常亮；OTA 进行中 1Hz 闪烁（优先于常亮）；否则熄灭
*
* 依赖：
* - BLE：usr_get_conn_service() != 0
* - COM：cdc_is_com_open() == 1（与 Dengle 暂停语义一致）
* - OTA：usr_get_ota_status() == 0（dual_ota_idle=0 表示忙）
