refactor: 重写黄灯故障指示 — 断开次数编码闪烁

Browse Source 
- 无线圈上电: 黄灯快闪 (200ms)
- 线圈断开 N 次: N 短闪 (80ms亮/200ms灭 × N, 1.2s间隔)
- 不计入上电前未接线的情况
- 删除旧状态机 (g_led_loop_reconnect 等 4 个变量)
- 新增 g_disconnect_count/active + g_fault_phase/tick

* - 无线圈上电：黄灯快闪（200ms 周期）
* - 线圈断开 N 次（N≥1）：N 短闪（N×80ms 亮，间隔 200ms 灭，长灭 1.2s 重复）
