fix(assistant): update translate assistant content handling for QwenMT model (#10306)

* fix(assistant): update translate assistant content handling for QwenMT model

- Adjusted content assignment in getDefaultTranslateAssistant to use store settings only when the model is not a QwenMT model, ensuring correct translation behavior.

* lint err

* refactor(assistant): encapsulate content handling logic for translation

- Introduced a new function, getTranslateContent, to streamline content assignment in getDefaultTranslateAssistant.
- This change improves readability and maintains correct translation behavior for QwenMT models.

* format code
