Forms Access - Decision History without Assess Item

**Description**

When a user has form decision-history view access but not item-decision access, they cannot view the decision history.
The decision history is coming through but not visible due to the structure of the form.

**Acceptance Criteria**
- [ ] Update the roles and the form to make sure decision history shows when the user doesn't have item-decision role.

Start by tracing the form's decision-history display and the roles controlling item-decision access. Reproduce the case with decision-history view access but without the item-decision role, then update the roles and form structure so the history is visible and verify both access combinations.
