As an associate, I want the Fetch Allocated Records API to return data that accurately reflects language preferences, so that the Closure screen displays the correct preferred language in the language list.

Reviewing and updating the Fetch Allocated Records API to ensure it includes the necessary language information tied to allocated records.

Acceptance Criteria:

• The API includes the preferred language field for each allocated record.

• Language filtering logic aligns with associate-level access and allocation rules.

• The Closure screen correctly displays the updated language list based on API response.

• Backward compatibility is maintained with existing API consumers.
