Usage Server Badge Meaning Red vs Green

### problem

On the Usage Dashboard, the badge next to the server name (see image above) may be interpreted as showing whether the server is Online (green) or Offline (red).

However, this is not what it represents. The badge actually indicates whether the Usage service is running on the same instance as the Management Server serving the UI.

As a quick improvement, we could add a tooltip to clarify this when hovering over the badge.

Suggestion:
```json
"label.usageislocal.tooltip": "Indicates whether the Usage Server runs on the same instance as this Management Server"
```

Please share your thoughts.

### versions

### What to do about it?

_No response_

从 Tools > Usage 开始，跟踪 Usage Dashboard 中服务器名称旁边的徽章，然后找到 label.usageislocal.tooltip 的本地化条目。添加建议的说明性工具提示，并验证将鼠标悬停在徽章上时，能够明确说明它表示 Usage 是否运行在与 Management Server 相同的实例上。
