Controller does not check if a promo code is valid.

Hi @didebru, I'm not used to this module much. Based on your proposal, I'm querying the existing data in table to validate and rendering message accordingly. Please review. Also attached the screenshot.

Thanks for your work but the issue is a bit more complex than this.
We have to check all we can check without the user and order context.
Also we should prompt an error message if the code is invalid.

Sorry I didn't see you started to work on this I have prepared a solution in another branch which works fine for me.

I've updated the MR to include dependent error messages also doing some sanity checks and take the coupon start end date into account.

Update the MR and remove core: 8.x from .info.yml.
