wangfq dfadc26717 fix(vd960DBN): MQTT buffer 从栈改为 static，防止栈溢出 (栈仅 2KB) ...

iot_mqtt_send_connect:  opts(~85B) + buf[256]  → static (~340B 省)
iot_mqtt_send_subscribe: buf[256]              → static (256B 省)
iot_mqtt_publish:        buf[2048]             → static (2KB 省)
调用链 WCHNET_HandleGlobalInt → iot_mqtt_handle_sock_int
→ iot_mqtt_send_connect 会叠加 WCHNET 协议栈内部开销，
2048B 栈极易溢出导致 hard fault（现象：乱码+truncated日志+重启）
