Reimplement the copy token ui

[zusorio]

Add a way to copy the token to the dashboard following #173

Love that UI lmao

Will look at it on my machine later

I wasn't a huge fan of the token button just sitting at the bottom of the dashboard, so I've hidden it in the user dropdown:

The dashboard and token buttons only show if the user has a production client. I think this is a slightly nicer place to hide it

Yeah, I agree that looks much better!
