fix(i18n): U30 修复 8 处批量 i18n 转换损坏的调用 — DeploymentEditContainers/DeploymentEditStorage/AgentRuleDialog/LogFieldSidebar

损坏原因: 早期批量正则 i18n 转换 (U20 记录的 i18n.t() 损坏模式遗留) 将模板表达式/JSX
碎片错误包裹进 i18n.t() 调用, 产生运行时垃圾文本渲染.

修复清单:
- DeploymentEditContainers.tsx:85 — toast 调用 description 字段损坏 (i18n.t('), description: ...'))
- DeploymentEditStorage.tsx:175 — !manifest 空状态文案损坏
- DeploymentEditStorage.tsx:202 — 数据卷卡片副标题损坏
- AgentRuleDialog.tsx:111 — DialogDescription 损坏 (i18n.t('>阈值 {ruleForm.metric !== '))
- AgentRuleDialog.tsx:157 — 操作符 Label 损坏
- AgentRuleDialog.tsx:183 — 端口 Label 损坏
- AgentRuleDialog.tsx:195 — 持续时间 Label 损坏
- LogFieldSidebar.tsx:68 — 搜索框 placeholder 损坏

新增 i18n 键 (zh/en 对齐 7370→7376 +6):
- agent.ruleDialog.description / operator / port / duration
- kubernetes.storage.volumeDesc
- monitor.lbl.searchFields
