[Queue-2.0] Split up courses on home page

Summary

Currently, all courses on the home page are displayed in one big blob. These should be split up into multiple blobs:

1. One for editions with active labs or slot selections.
2. One for showing the editions currently running, and your role in them.
3. One for showing editions that are finished.
4. One for editions that are archived, optionally this could be made more hidden for students.
