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

ACS 4.20.2, but not limited to.

### The steps to reproduce the bug

1. Navigate to Tools > Usage

### What to do about it?

_No response_

Tools > Usage から始め、Usage Dashboard でサーバー名の横にあるバッジをたどり、次に label.usageislocal.tooltip のローカライズエントリを見つけます。提案された説明用ツールチップを追加し、バッジにカーソルを合わせると、Usage が Management Server と同じインスタンス上で実行されているかどうかを示していることが明確になることを確認します。
