misc: unify coupons experience

[ansmonjol]

Context

We figured out we had discrepancy in the coupon actions over the app.

1. You were able to terminate a coupon anytime from the details, but not from the coupon list (conditionally)
2. You were not able to terminate a coupon from the details page

Description

This PR fixes those and also

• displays the coupon status in the details page. After adding the terminate action it was blurry about the coupon status there.
• make sure active queries (coupon details, delete or terminate coupon) are not fired again after a coupon is deleted. That used to trigger an error modal in the app before redirection to coupon list
• display the correct wording in the delete coupon modal depending if the coupon have been applied to a customer or not

Fixes ISSUE-620
