fix(v0.11): 第六轮走查——legacy 去除 System.out 演示入口与 Kafka 消费端日志

- AESUtils / RSAUtils / SM4Utils / CustomXssUtil / SnowFlakeSerialCode：删除仅用于本地演示的 main，消除生产源码中的 System.out。
- KafkaConsumer：移除 printStackTrace；异常改为 logger.error(msg, e)；Class.newInstance 改为 getDeclaredConstructor().newInstance()。

对应 docs/reviews 05 工程卫生项；全量 maven-cloudwalk-legacy-public 已通过 compile。
