Make B2B orders as draft orders first

Currently, B2B orders are created as finalized orders immediately after checkout. This limits the ability to make changes or adjustments before processing the order further.

Use case:

In B2B scenarios, customers often pay using invoice or “net terms” (e.g. 30 days). In these cases, merchants typically need to review and adjust orders before finalizing them. This may include modifying products, applying custom discounts, or handling specific pricing agreements.

Proposed solution:
Allow B2B orders to be created as draft orders instead of finalized orders when customers choose payment methods such as invoice or net terms. These draft orders should remain fully editable before being completed.

Expected outcome:
Merchants gain more control and flexibility in handling B2B orders, enabling accurate order management, smoother invoicing workflows, and better alignment with standard B2B processes.
