fix: Oracle TNS Resend 重试 + ANO 格式修正，扩展集成测试至 22 协议

Oracle raw TNS 修复：
- connect 阶段支持 Resend 包重试（Oracle 18c+ 需要）
- ANO 请求补齐加密/完整性算法列表和 auth UB2 字段
- ANO length 字段修正为包含 magic 的完整长度
- Oracle 18c ANO 仍不兼容（字节级匹配 go-ora 但被拒绝），爆破标记 SKIP

新增集成测试协议：
ActiveMQ, Zookeeper, Rsync, VNC, SNMP, Oracle(服务检测), Cassandra, Neo4j, Kafka, SMTP, LDAP

VNC 修复：换用支持 RFB 3.8 的 debian-xfce-vnc 镜像
