整合 /srv/监控架构优化方案 核心代码： 后端模型（4个新文件）： - monitor.go: MonitorTarget(统一监控目标) + MonitorMetric(指标定义) + MetricValue(时序数据) + MetricHistory - snmp.go: SNMPDevice + SNMPTemplate + OID模板管理 - site.go: SiteTask(拨测任务) + SiteResult(拨测结果) - alert_v2.go: 增强告警(多条件规则/模板/升级策略/静默) 后端 pkg（3个包）： - pkg/prometheus/client.go (531行): PromQL查询/Range/Labels/Rules - pkg/zabbix/client.go: Zabbix API (Host/Item/Trigger/History) - pkg/snmp/collector.go (621行): gosnmp Walk/BulkWalk/自动发现 基础设施： - Dockerfile: Go 1.21→1.24 (gosnmp依赖) - Agent安装弹框: SSH一键安装Tab + server上下文 - 服务器列表操作栏: 安装按钮条件显示/隐藏 Handler层因类型不兼容暂时跳过，模型和客户端包已编译通过。
