Units can be copy-pasted from a library into a course

@sdaitzman could you please flesh out this issue? We'll want to ensure that for Teak, it's at least possible to copy-paste units into a course so that there is some way to use the new units functionality before we implement the full Epic 14 workflow.

@bradenmacdonald I'm concerned about adding copy-paste support to units because of the added complexity. Would we have to keep track of two (eventually four) clipboards for different levels of content? Or, would we end up in a situation where you can have a clipboard that can't be pasted in a context with a paste button?

Let me know if I'm overthinking this, or missing some reason to prioritize copy-paste support for units— I was planning to defer this to a later epic to build out that logic.

@sdaitzman We already support copy-pasting units among courses in the platform. There is very little new functionality here, only adding a "Copy" button to the UI.

I think you're overthinking it a bit perhaps. We have only one clipboard, and the paste button on the course outline page is only enabled if you have a unit in the clipboard. The paste button on the unit page (to paste a component) is only enabled if you have a component in the clipboard. You can try this out in courses in Studio today.
