Refactor ci minutes progress bar - pt2

What does this MR do?

Related to #213964 (closed)

This is the 2nd part of the refactoring continued from !30276 (merged)

In this MR we are using the ci_minutes_progress_bar helper for extra minutes introduced in !30276 (merged).

We are also tidying up the code by removing entirely the logic in the helpers in favor of using Ci::Minutes::Quota for calculations. The helpers are now a very simple presentation layer, as they should be.
