Forbid self-approval (four-eyes)

When on, whoever submitted the approval request cannot decide on it themselves – the flow needs two different people. An admin can always unblock a flow stuck because of this with the Admin override button.

The checkbox is in the policy editor and applies to the whole policy, every step of it.

• The submitter cannot decide their own request even if they would otherwise be the step's approver, hold the right as a delegate, or are the escalation person.
• They get no reminders about their own request either.
• If a step has a single approver and that person submits the request, the flow can get stuck. A warning on the policies page points this out.
• For a stuck flow, an admin can force-approve, force-reject or cancel it from the request with the Admin override button; a reason is required.
• Automatic approval under the threshold involves no human decision, so the rule plays no part there.
