Learning Paths now shows what you'll be able to do, and you can archive paths

Two additions to Learning Paths:

- Every path now opens with a clear "By the end of this path, you'll be able to..." list, so you know what you're actually getting before you start. - Started a path you're not actively working through anymore? You can now archive it from the path page. It disappears from your Continue Learning card and profile without losing your progress — and you can unarchive it any time.
