feat(i18n): 增量国际化迁移 — deploy/kubernetes/monitor/task 全模块 + 补全 28 缺失翻译键

迁移范围:
- deploy 模块 (PipelineEditor/PipelineDetailDialog/PipelineFormDialog/PipelineRunDialog/ReleaseCreateDialog/ReleaseDetailDialog/ReleaseManager/ToolConfigTab/JobRoleCreateDialog 等 14 文件)
- kubernetes 模块 (YamlEditorToolbar/DeploymentHpaTab/DeploymentLogsTab/DeploymentPodsTab/DnsHostSection/SchedulingSection/EventsTab/HPACronHPATab/HistoryTab/PodsTab/ServicesTab/ActionModals 等 12 文件)
- monitor 模块 (AlertEventsTab/AlertCenterDetail/DatasourcePage/LogAlertBell/LogCenter/LogCenterArchBanner/StatChartPanel/LogRoleCreateDialog 等 8 文件)
- task 模块 (CronJobStatsPanel/CronJobTable/CronJobViewDialog/ExecutionHistoryDialog 4 文件)
- layout (PageEmpty/PageLoading 2 文件)
- site-monitor/snmp-monitor 模块 (6 文件)

翻译键: 3975 → 4003 (+28 缺失键补全), 22 命名空间, zh-CN/en-US 完全对齐
新增命名空间: agent/aiops/cloud/kubernetes/monitor/pipeline/rbac/system/task/ui

验证: go build✅ tsc -b=0 npm build✅ (20.78s) 17/17 集成测试通过
