Resolved issues and error corrections
Odoo now prevents customers from using an eWallet or gift card reward to pay for that same program's top-up product. This closes a loophole where users could increase their stored balance using the balance itself, protecting businesses from incorrect credits and revenue loss.

### Steps to reproduce:
- Download 'Sales' application
- From 'Configuration' > 'Settings', enable 'Promotions, Loyalty & Gift Card'
- From 'Products' > 'Gift cards & eWallet', Configure an eWallet program with a top-up product
- Have a customer with an existing eWallet balance
- Create a new sale order for that customer and add the eWallet top-up product
- Pay the order using the customer's eWallet
> The order gets discounted by the eWallet, effectively allowing the user to top up their balance
using the balance itself (infinite money glitch).
### Cause of Issue:
When computing the discountable amount for payment programs (like eWallets and gift cards), `_discountable_order` includes the total order amount. However, it did not exclude the program's own top-up products (`trigger_product_ids`) from the discountable lines.
### Fix:
If an order consists solely of top-up products, attempting to apply the eWallet now correctly raises a `UserError` ("There is nothing to discount").
