feat: V1.03 initialize 上线消息 — 固件+工具同步

vd960DBN:
- dev_initialize_pub() 改为 V1.03 格式 (msg_id/cmd/ts/data/extra_info)
- iot_mqtt_srv: 订阅改双主题 dld960/{sn}/srv, 响应 topic 改 dev
- SUBACK 后自动发 initialize 告知服务器上线
- net_srv.h: 加 dev_initialize_pub 声明

DBNMQTTool:
- protocol.py: 加 CMD_INITIALIZE
- device_manager: DeviceInfo 加 extra_info, 加 mark_online()
- main.py: 接收 initialize 消息, 自动标记设备上线
- docs: 协议 V1.03 + devlog V3.1
