refactor(iot_mqtt): 清理死代码+合并 buffer, BSS 节省 ~5.5KB
1. _iot_send_buf[1024]: 移除 (全局搜索无引用)
2. _iot_recv_buf[1024] + _iot_wchnet_buf[1152]: #if 0 包裹 (仅死代码引用)
3. 3 段死函数 #if 0 包裹:
- iot_mqtt_send_connect / subscribe: static buf[256]×2 + opts(~85B)
- iot_handle_publish / suback / process_recv: static json[1024]
- iot_send_heartbeat / connect / handle_sock_int / poll: 栈变量全部消除
4. data_json[1024]+payload[1024] → g_sensor_buf[1400]:
