AUTH - changes related to commissioners for taking affidavits

This is the parent epic

**BACKGROUND**
Commissioners are appointed by the position in gov – BC ones can be searched in the GAL.

Wendy’s team is already accepting these & have a process that meets their needs. The challenge is the form doesn’t allow for it currently.

Review the form flow and the existing GAL search and acceptance process described in the issue. Clarify with Wendy’s team how commissioners appointed by position should be represented and what the form must support; done means the form accepts the process they already use.
