refactor(i18n): U39 残余 JSX 属性/模板字面量中文清零 — 14 处→0

10 文件修复:
- DualLineChart: subtitle 接收/发送→i18n.t(monitor.lbl.receiveSend)
- NetworkTab: 5处 unit="个"→t(common.unitCount)
- FDUsageCard: subtitle 当前→t(monitor.lbl.currentFDUsage)
- NamespaceOverviewPage: subtitle 命名空间概览→i18n.t(k8s.nsOverview.subtitle)
- NamespaceManagementPage: subtitle 资源配额→i18n.t(k8s.nsMgmt.quotaSubtitle)
- CreateHPADialog: title+text 命名空间→i18n.t(k8s.hpa.targetInfo)
- LogFieldSidebar: title 个值→i18n.t(common.fieldValues)
- LiveMonitorDialog: title 全屏/退出全屏→t(common.fullscreen/exitFullscreen)
- ExecutionHistoryDialog: title 成功/失败→t(task.execHistory.successFail)
- LdapSettingsTab: className 成功检查→ldapTestSuccess boolean 状态

新增 11 翻译键 (common.unitCount/fieldValues/exitFullscreen/fullscreen +
monitor.lbl.receiveSend/currentFDUsage + k8s.nsOverview.subtitle/nsMgmt.quotaSubtitle/hpa.targetInfo +
task.execHistory.successFail), zh/en 7751→7762 对齐
