fix: 恢复1.20版SaaS连接核心代码，修复Agent无法连接SaaS服务器问题

问题根因：1.21代码优化时误删了SaaS连接核心组件
- 误删 MultiTargetNettyClient.java (Netty TCP客户端)
- 误删 ConnectionConfig.java (连接配置封装)
- 误改 AgentNettyConfig 配置前缀从 netty.server 改为 tcp.netty.charge
- 误删 AppInitializer 中的SaaS连接初始化逻辑
- 误删 AgentService 中的 connection() 等接口方法
- 误增 AgentNettyServer.java (1.20中不存在的服务端类)

修复内容（从1.20原版JAR反编译恢复）：
- 恢复 MultiTargetNettyClient: Bootstrap.connect() 主动连接SaaS服务器
- 恢复 ConnectionConfig: 连接配置封装类
- 恢复 AgentNettyConfig: @ConfigurationProperties(prefix = "netty.server")
- 恢复 AppInitializer: CommandLineRunner.run() 调用 initConnection()
- 恢复 AgentService/AgentServiceImpl: connection()方法及全部业务接口
- 恢复 MachineFingerprint: 硬件指纹生成工具类
- 恢复 application-dev.yml: netty.server.host/port 配置
- 删除 AgentNettyServer.java (1.21错误新增)
- 删除旧 AgentNettyConfig.java (tcp.netty.charge 前缀)

部署验证：39.96.218.1 已成功连接SaaS服务器 120.211.95.173:6620
