The current implementation of the Account Vanishing flow, has the "rejection reason" field set as optional.
After discussion with the team and approval from the Steward, we would like to make this change and ensure that the field is "required".
AC:
- Make the field required for the manual flow
- Make sure that the automated flow (that is run when someone has a block) already has a reason and does not break with the above change
- Ensure the field is not affecting the normal "approved" flow (both manual and automatic)
