Add banned/blocked indicator to GitLab.com card matches admin page

What does this MR do and why?

• Adds (banned) and (blocked) texts, when applicable, next to the username in ee/app/views/admin/users/card_match.html.haml

This same feature was implemented for the similar view ee/app/views/admin/users/phone_match.html.haml in this MR: !139083 (merged).
This feature helps the Trust and Safety team investigate bad actors that create multiple GitLab users on GitLab.com with the same credit card info.

How to set up and validate locally

1. Simulate a SaaS instance

2. From the rails console, create matching card validation data for 3 users:

   Users::CreditCardValidation.create(user: User.find_by_username("reported_user_1"), credit_card_validated_at: Time.now, holder_name_hash: "foo")
   Users::CreditCardValidation.create(user: User.find_by_username("reported_user_2"), credit_card_validated_at: Time.now, holder_name_hash: "foo")
   Users::CreditCardValidation.create(user: User.find_by_username("reported_user_3"), credit_card_validated_at: Time.now, holder_name_hash: "foo")

3. From the Admin Area, ban one of the users from the previous step, and block another one.

4. In the Admin Area, go to the profile page of one of the users (for example: http://gdk.test:3000/admin/users/reported_user_1). Scroll down to the Credit Card section and click on View card matches.

5. Check that, next to the username, one user has the (banned) text, another user has the (blocked) and the third user has no text. (One of the users will have the (this user) text).
