refactor(i18n): U41 残余硬编码中文清零 — 工具函数+审计RDP标签+AIOps分析+Monitor残余+审批选项

18 文件 ~35 处 UI 硬编码中文→t()/i18n.t() 调用:
- agent-utils.ts timeAgo() 秒前/分钟前/小时前
- utils.ts formatDistanceToNow() 分钟前/小时前/天前
- request.ts 响应解析失败错误消息
- ActiveSessionsPanel/HistorySessionsPanel RDP 在线/历史会话标签
- MetricsExplorer 清除/已选/最近1小时
- HostMonitor 当前主机 subtitle
- AIAnalysisResult 证据链 (新增 useTranslation hook)
- capacity-predict.ts 容量预测摘要模板
- ApprovalResourcePage 阿里云/腾讯云/华为云
- ApprovalPermissionPage 堡垒机
- site-monitor/helpers.ts 频率/时间/证书天数格式化
- site-monitor/analytics.ts 证书剩余/检查失败/延迟波动事件
- middleware-monitor MwTargetChartsPanel/MwTrendChart/helpers.ts
- snmp-monitor SnmpMetricTrendChart/SnmpDeviceChartsPanel
- host-monitor/utils.ts 图表点数标签 + PortPolicyDialog 系统进程说明
