feat(vd960DBN): TCP JSON协议服务 — 端口5960, 鉴权+15条命令

- net_config.h: TCP_LISTEN=0→1, TCP=2 支持 JSON 监听
- 新增 tcp_json_srv.h/c: 行分隔 JSON, pwd_verify鉴权, 命令分发
- 实现15条协议命令: dev_info/ssc_net/iot_net/iot_topic/pwd_set/factory_reset等
- loop_param_set/query 接受命令返回stub(Loop MCU中继待实现)
- net_srv.c: 集成 JSON 中断路由 + init
- peripheral_main.c: 主循环 tcp_json_poll()
