### The Feature

I would like the LiteLLM Admin UI to support internationalization through a standard i18n framework.

Desired behavior:

1. UI text is moved from hardcoded strings into translation resources. 2. Admins can configure the default UI language. 3. Users can optionally switch language in the UI. 4. English remains the default language. 5. Community contributors can add language packs such as Chinese.

This feature request is for the i18n framework and structure first, not necessarily for full translation coverage in the initial PR.

### Motivation, pitch

LiteLLM is used by global teams. In many enterprise deployments, internal users and admins may prefer a localized dashboard.

Without an i18n framework, local deployments often need to patch hardcoded UI strings directly, which creates long-term merge conflicts when upgrading LiteLLM.

A standard i18n structure would make localization maintainable and allow the community to contribute translations incrementally.
