Make steps usable standalone
The previous refactor was close but we needed a bit more refactoring to make a single step usable on its own, as it will be used in the link handler. The main problem was the wrapper that had both steps in it, we would have to pass in the steps instead which brings us back to that whole generalization problem where a step has types that lead into the next step's init. The solution is to remove the wrapper and wire up the steps wherever they are needed, whether that is one step or multiple, and the main change to make that possible is to move the buttons into each step rather than having them in a wrapper component. Now you can create any single step and use its output. This is used in the link flow and the buttons in the step now replace the default buttons in the dialog wrapper.
