As an associate, I want the Re-allocation API to follow the correct introductory allocation logic, so that when a call is re-allocated, the language preferences are preserved and accurately reflected on the Closure screen.

Ensures that the Re-allocation API applies introductory allocation rules properly during re-allocation, especially regarding language matching.

Acceptance Criteria:

• The API logic uses introductory allocation parameters.

• Preferred language is correctly retained or reassigned in re-allocation scenarios.

• Closure screen reflects the updated and correct preferred language post re-allocation.

• No impact on re-allocation logic for other user roles or call types.
