Improve Order detail layout / configurable sections (Ops view)

[Doulami]

Problem: Order details are split across multiple areas; ops must scroll/jump between fulfillment, shipping, payments, history. This slows down fulfillment and increases mistakes.

Request: Provide either:

a configurable layout for the Order detail page (reorder/hide sections), or

a built-in “Ops View” tab that groups Shipping + Fulfillment + Payments + Actions in one place.

Why this matters: high order volume workflows; warehouse staff needs one screen.

Acceptance criteria:

Ability to reorder sections OR select between “Default view” and “Ops view”

No breaking changes to data model/API

Works with custom fulfillment handlers and custom payments

Extra: If there’s already an Admin UI extension point for injecting components, could you expose official “slots” for where to render built-in sections?
