Enhance CreateProductDialog and MerchantStore components for product editing functionality

- Update CreateProductDialog to support both creating and editing products, with dynamic button text and pre-populated fields for existing products.
- Refactor product submission logic to handle updates, including error handling and user feedback.
- Modify MerchantStore to manage product editing state and integrate updated product handling in the dialog.

These changes improve the user experience by allowing merchants to easily edit existing products, enhancing the overall product management workflow.
