feat(audit): F1+F2 告警静默规则标记完成 + 审计日志CSV导出实现

F1 告警静默规则 [done]: - 后端 alert_silence.go: CRUD + Toggle (onetime/daily/weekly 三模式) - 告警引擎 isSilenced 集成 (alert_engine.go) - 前端 SilenceRuleTab + SilenceDialog - 路由 /alerts/silences 已注册 F2 审计日志导出 [done]: - 重写 ExportAuditLogs: 真正的 CSV 导出 (encoding/csv + UTF-8 BOM) - 支持 module/action/username/startTime/endTime 筛选 - 导出限制 10000 条防溢出，自动记录审计日志 - JSON 格式向后兼容 (format=json) - 前端 exportLogs 传递查询参数同时包含累积的前期工作: - 目录重构 internal/ -> controller/model/router (v0.55-v0.57) - 后端分层架构 dto/repository/service/utils - 审计模块全功能 (终端审计/操作审计/登录日志) - asciicast v2 录制格式 - SFTP 文件浏览器 - StatStrip 紧凑统计条 - 在线会话自动刷新 - LiveMonitor WebSocket 诊断修复验证: go build ✅ | npm run build ✅ | Docker 部署 ✅ | 10 回归端点 ✅ | CSV 导出 ✅ | 静默 CRUD ✅
