[Bug] Zibal driver ignores optional parameters like mobile, description, etc.

[amiriaa1]

Problem

In the Zibal driver (src/Drivers/Zibal/Zibal.php), the purchase() method builds the POST payload manually and doesn't include optional parameters like:

• mobile
• description
• allowedCards
• etc.

Even though the method checkOptionalDetails() exists for this purpose, it is never used.

Why it matters

When we set these values using:

$invoice->detail([
    'mobile' => $user->phone,
    'description' => 'Test order'
]);


$data = [
    'merchant'    => $this->settings->merchantId,
    'amount'      => $amount,
    'callbackUrl' => $this->settings->callbackUrl,
    'orderId'     => $orderId
];

$data = $this->checkOptionalDetails($data);

CURLOPT_POSTFIELDS => json_encode($data),
