refactor(i18n): U32 全量 hash key 清理 — 151 个 hash key → 语义化键 + React Hooks 警告 53→43

- 151 个 hash-style flat key (s+hex 后缀) 全部重命名为语义化 nested key
  - monitor 58 个: alertChannelDialog/alertManager/alertRulesTab/chartRangeHint/
    esIndexPicker/helpers/hostMonitor/logAlertSpanel/logClusterPanel/logDingAssistant/
    logQueryToolbar/logRbac/lokiLabelBrowse/metricsExplorer/middlewareMonit/
    mwOverviewChart/portPolicyDialog/prometheusDashb/queryHistoryPan/savedQueriesPan/
    siteMonitor/snmpMonitor/snmpOverviewChart/zabbixDashboard/zabbixDatasource
  - kubernetes 42 个: deploymentBundle/deploymentEditAdvanced/deploymentEditService/
    deploymentView/deploymentWorkload/eventsPage/kubernetesCluster/namespaceManage/
    namespaceResource/podExecTerminal/podFileBrowser/podLogsViewer/podMetricsPage/
    resourceVisualEditor/workloadViewPage
  - aiops 17 个: agentCliMessage/aiAnalysisResult/analyzerHelpers/assistant/predictUtils
  - agent 12 个: agentAlerts/agentMonitor/hostDetailDialog
  - cloud 13 个: billingRecordDialog/billingRuleDialog/platformManager
  - pipeline 6 个: buildNodesManage/deployRbac/deployTargetField
  - system 3 个: auditSetting
- 58 个源文件中的 147 处 t()/i18n.t() 调用更新为语义化键路径
- 3 个命名空间冲突修复 (monitor.hostMonitor/agent.agentMonitor/aiops.aiAnalysisResult
  原 string 值提升为 .title 子键)
- React Hooks 警告修复 (53→43, -10):
  - exhaustive-deps 4→0: useMemo/useCallback 添加 t 到 deps 数组
  - preserve-manual-memoization 5→0: 变量遮蔽修复 (filter(t)→filter(tg))
  - 1 个冗余 eslint-disable 指令移除 (CronJobManager)
- zh/en 7480=7480 完全对齐, 0 个 hash key 残留
- tsc -b=0, npm build✓ (17.59s), ESLint errors=0/warnings=43/any=0
- go build=0, 17/17 集成测试通过, Docker healthy
