fix(promotions): include campaign.budget.type in status_display requiredFields

[okxint]

The status_display computed column for Promotion lists requiredFields
that drive the API fields= query. It requests campaign.budget.limit and
campaign.budget.used but omits campaign.budget.type.

getPromotionStatus() checks budget.type to decide whether to skip the
exhausted-budget check for use_by_attribute / spend_by_attribute budget
types. Because type is never fetched, it receives undefined, falls
through to the overBudget branch, and marks otherwise-active promotions
as "Campaign expired".

Adding campaign.budget.type to requiredFields ensures the type is
available when getPromotionStatus() evaluates the promotion status.

Thanks for the contribution! We need more information before reviewing this further.

Correctly fixes a missing field in the Promotion status_display computed column that caused promotions with per-attribute budgets to be incorrectly marked as expired. The one-line change is well-reasoned and targeted. However, the PR body replaces the required template with free-form prose — the Testing section is absent — and no changeset is included.
