* fix: [MICROBA-1769] Cert status before course end
Right now, learners who are nonpassing are able to view information
about thier certificates early at the course end screen and progress
pages. This is because we show messaging around the nonpassing state in
some cases before a course ends and certificates are available. This can
also lead to cases where grades are not finalized and students who may
be passing see a scary nonpassing message instead.
This change makes it so during the course exit, a student who finishes a
course before the course is over will see the celebration screen
regardless of passing status. Once the course is over (or if
certificates are available immediately), and they are
still not passing, they will see the nonpassing messaging. The same
change was made for the certificate status alert in the progress tab.
Specifically, a "I visited this page" event, with information on
which variant was seen. And "I clicked this button" events, for
our various calls to action.
- Adds a non-passing cert learner course exit screen
- Moves all the logic about what course-exit mode we're in into
a utility method in the course-exit folder
- Moves all the logic about how the 'Next' button should read into
a utility method in the course-exit folder
