International Loan system update

The international loan system has been updated with significant changes to enhance realism and user engagement. The previous variable interest rate structure has been eliminated and replaced with a simplified fixed-rate system. Under the new framework, borrowers can now select from two clearly defined options: a 5% interest rate for loans with 32 installments, or a 2.5% interest rate for loans with 16 installments. 

These modifications aim to provide a more straightforward and immersive financial experience within the trade center environment.
