Import Order State into Order Details Page in Dashboard Stepper

Currently, despite orders working and completing, the order details page doesn't display anything. I would prefer a user experience that has explicit displays of important data like the details of a completed order. This is part of a larger UX mindset this project requires where users need to really feel in control of the trade flow and understand each step.

Start by locating the order details page and dashboard stepper entry points, then trace how completed orders expose their state and details. Confirm which data should be displayed with the maintainers; done means the page explicitly presents the agreed completed-order information and each relevant trade-flow step.
