[woocommerce] define several callback URL at the different steps of redemption process

[levalleux-ludo]

At the moment, there is a callback URL call when the delivery information is submitted We need another call after the redeem transaction is submitted and another when the redeem transaction is confirmed. In addition, we need these calls to handle the possible errors, like:

• an error occurred in the backend when the delivery info is submitted --> the widget needs to show an error occurred and shall not continue with the redemption step
• an error occurred when the transaction is submitted --> the error is sent to the backend, instead of the submitted transaction
• the transaction is reverted --> the error is sent to the backend, instead of the transaction confirmation
