chore: update iyzico payment processing and database schema

Enhanced the iyzico payment processing logic by updating the handling of checkout form content. Modified the order schema to include a new field for storing the checkout form content, ensuring it persists across page refreshes. Updated related functions to reflect these changes, improving the overall payment experience. Additionally, updated the app database to incorporate the latest changes.
