litellm - 💡(How to fix) Fix Feature Request: Add Chinese (Simplified) language support / 添加简体中文语言支持

Feature Description / 功能描述

LiteLLM 目前的管理界面（Dashboard UI）仅支持英文。为了让中文用户更好地使用该平台，希望添加简体中文（zh-CN）的语言切换支持。

LiteLLM's admin dashboard currently only supports English. For better user experience for Chinese speakers, we would like to request adding Simplified Chinese (zh-CN) language support to the UI.

Use Case / 使用场景

• Chinese-speaking development teams can use the dashboard more efficiently
• Easier onboarding for team members who prefer Chinese interface
• 中文开发团队可以更高效地使用管理界面

Suggested Implementation / 建议实现方式

1. Use i18next or similar internationalization library for the React dashboard
2. Add translation files for zh-CN
3. Add language switcher in the UI settings

Example libraries that could be used:

• i18next (https://www.i18next.com/)
• react-i18next (https://react.i18next.com/)
• next-i18next

Additional Context / 其他信息

• The dashboard is located at: ui/litellm-dashboard/
• Framework appears to be Next.js
