Fix spacing and UI on Recent Deliveries section of Project Services

What does this MR do?

Issue #118791 (closed)

Example URL: http://localhost:3000/gitlab-org/gitlab-shell/-/services/jenkins/edit

• Remove negative bottom margin on .footer-block that pushes content up. Add 32px top margin to the Recent Deliveries section.
• Use .badge instead of .label for the status code to have rounded corners.
• Use a label method to show just "Error" instead of "internal error" on the frontend.

Other places that use .footer-block

Below are a few places that use the .footer-block CSS class. This MR made a change to the bottom margin so below are screenshots to show that those do not have visual regressions. Thankfully, most of them are meant to be at the bottom of the page (aka "footer") so there is only whitespace below.
