fix(i18n): 全站文案书面化 + 中英翻译质量修复

中文(zh):约 40 处口语化改书面(「谁在什么时候改了什么」→「操作人、时间与变更前后对比」、
「找出最吵的业务」→「定位日志量最高的业务」、「点」→「点击」、创建你的第一个→创建首个等);
「副本 / Pod」统一为「Pod」。

英文(en)修复:
- 功能 bug:wizard openGrafana ({url}) 插值失效→({{url}});settings notify 空态链接词悬空破句
- 语义补齐:clusters/hosts 删除确认补 Warning 与后果句;tokenInsecureHint 补 Kubeconfig 建议
  (并删 en 死键 tokenRecommended);retention liveHint/costWarning/upgradeHint 补丢失半句
- 术语统一:data source / collection policy / log lines / Listen IP (internal) / Total deployments
- 复数:users confirmDesc、pagination total、range lastMinutes 补 _one;storage deleteWarning 两形态对齐
- 风格:Select filtered users、Delivery History、Log Scrape Jobs、App label source、
  Deployment Logs 连字符改间隔号;删除 zh 死键 liveTitle
