fix: 修复 Copilot 作为 Claude 时 OpenAI 模型的 Responses 分流 (#1735)

* fix: route copilot claude openai models to responses

* fix(i18n): add copilotProxyHint translation key for all locales

The copilotProxyHint message was using inline defaultValue with Chinese
text, which would show Chinese to English and Japanese users. Added
proper translation keys in zh/en/ja locale files and removed the
hardcoded defaultValue fallback.
