Changes to GET `/api/v0/main-frontend/course-credit-registrations/courses/{course_id}/summary` - Per-module counts plus the two reasons a student of this course will not get credits. Course-wide unless `course_instance_id` narrows the per-module counts to one instance. The two student-number totals are course-wide either way: a student holds one number, not one per instance.
