Add Simplified Chinese (zh-CN) admin locale (#471)

* Add Simplified Chinese (zh-CN) admin locale

Enable the zh-CN locale across the admin UI: add "zh-CN" to lingui.config.ts locales, register { code: "zh-CN", label: "简体中文" } in the admin SUPPORTED_LOCALES, and add the initial messages.po with Simplified Chinese translations at packages/admin/src/locales/zh-CN/messages.po. This provides localized strings for the admin interface.

* docs(locales): Update the Chinese translation file and add missing translation content.

* style: format

* style: format

* Add Arabic locale support to configuration
