🐛 Fixed an issue that didn't show the correct plan when on the billing edit page for the old payment provider.

🎨 Update the design of the edit billing page, for the old payment provider, to be similar to the new one launched the other day. Also added a note saying that upgrading is not possible right now with the old payment provider — will work on this at some stage.
