feat(i18n): add multilingual support for provider components

- Add i18n translations for proxy test button, model selector, and model redirect editor
- Support 5 languages: zh-CN, en, ja, ru, zh-TW
- Replace hardcoded Chinese strings with useTranslations hooks
- Add 41 translation keys across 3 component modules (proxyTest, modelSelect, modelRedirect)
