Fix inaccurate Chinese translations for wanStatus field in pfSense widget

[KuuDS]

Proposed change

In the pfSense widget, the Chinese translations for the wanStatus field values up and down are inaccurate.

The current translations are '上传' (which means upload) and '下载' (which means download).
I have replaced them with '连接' (which means Connected) and '断开' (which means Disconnected) respectively.

Type of change

• New service widget
• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Documentation only
• Other (please explain)

This change only involves I18n modifications and does not affect functionality.

Checklist:

• If applicable, I have added corresponding documentation changes.
• If applicable, I have reviewed the feature and / or service widget guidelines.
• I have checked that all code style checks pass using pre-commit hooks and linting checks.
• If applicable, I have tested my code for new features & regressions on both mobile & desktop devices, using the latest version of major browsers.

Sorry, I was a bit hasty. After submitting the draft, I found that the pfsense-related translations are included in zh-CN, zh-Hans, and zh-Hant. The translations in zh-Hans and zh-Hant are correct. We need to confirm whether to remove the translation in zh-CN or to correct it.
