Subject: [PATCH] [FIX] sale_coupon: Prevent users to modify the reward line
 product

Purpose
=======

People doesn't understand that the reward line product is the product that will be used in the discount line, not the product the be rewarded

If they set another product before the program is created, the product they set will be renamed, which is wrong.

Specification
=============

- Don't display the field before it's set
- Make the field readonly on the program form view
