Fix: Prevent exit from blocking redirect on QR payments Issue #11

[AayushN01]

This PR fixes an issue with Fonepay QR code payments where users are not redirected to the order success page after completing a payment, and the order status remains stuck at Pending Payment.

In the payment_status_completed($order, $response) method, an exit statement was present:

if ($order->has_status(wc_get_is_paid_statuses())) {
    WC_Gateway_Fonepay::log('Aborting, Order #' . $order->get_id() . ' is already complete.');
    exit;
}

This caused the redirect stuck in the blank screen without returning to the intended redirect url.

Solution:

Replaced exit; with return; in the payment_status_completed method:

if ($order->has_status(wc_get_is_paid_statuses())) {
    WC_Gateway_Fonepay::log('Aborting, Order #' . $order->get_id() . ' is already complete.');
    return;
}

This allows the redirect to the success page to proceed properly, and ensures the order status updates correctly.

Steps to Reproduce:

• Add a product to the WooCommerce cart.
• Checkout using Fonepay and select QR payment.
• Scan the QR code and complete the payment.
• Before fix: Blank screen; order remains at Pending Payment.

After fix: Customer is redirected to WooCommerce success page; order status updates to Processing/Completed as expected.

Thank you @AayushN01 for the patch.

However, we can not merge this for now. Since the Fonepay's sandbox portal is still dis-functional, we are unable to keep plugin tested and up to date.
