feat(i18n): 安全审计模块全量国际化 — 7 文件硬编码中文改翻译键 + audit 命名空间(89 键)

迁移文件:
- AuditOperationsTab.tsx — 操作审计(搜索/筛选/虚拟滚动表格/详情弹窗/统计弹窗)
- TerminalAuditTab.tsx — 终端审计子标签(在线/历史/命令)
- LoginLogsTab.tsx — 登录日志(DataTable + 状态筛选 + 登录方式)
- ActiveSessionsPanel.tsx — 在线会话(自动刷新 + 阻断确认 + 实时监控)
- HistorySessionsPanel.tsx — 历史会话(回放/下载录制)
- SessionCommandsPanel.tsx — 会话命令(虚拟滚动)
- helpers.tsx — formatDuration/getStatusBadge (i18n.t 非组件模式)

翻译键: audit 命名空间 89 键 (operations/login/terminal 三子域)
  + common.duration 时长单位(秒/分/时)
总键数: 481→610, 命名空间: 8→9 (common/menu/header/login/dashboard/server/alert/approval/audit)
zh-CN/en-US 完全对齐, tsc -b=0, npm build✓, 17/17 测试通过
