Bytenet Static QR Payments with IRIS for WooCommerce

This plugin adds a new “IRIS” payment method to the WooCommerce checkout.

How it works:

1. The merchant uploads, in the gateway settings, the image of their personal
   or business static IRIS QR code (the one generated by their banking app —
   e.g. myAlpha, Eurobank Mobile, winbank, the IRIS app, etc.).
2. At checkout, if the customer selects “IRIS” as the payment method, they
   see this QR code and the payment instructions configured by the merchant.
3. The customer scans the QR code with their banking app and pays outside of
   WooCommerce (IRIS does not offer a public payment-confirmation API without
   a merchant agreement with a bank).
4. The order is automatically placed in “On hold” status.
5. Once the merchant sees the payment land in their bank account, they
   manually change the order status to “Processing” or “Completed”.

Important: because IRIS does not provide a public payment-confirmation API
without a bank merchant contract, this plugin does NOT automatically confirm
payment. If you have IRIS Business API credentials from a bank, automatic
confirmation via webhook could be added in a future version.
