Enable Point of Contact in Huntress portal to be a non-admin user.

Currently the Point of Contact must be a Huntress Admin, which means that we need to allocate Huntress Admin access to a user's standard email address, as that address is the best contact for Huntress to reach out to during an incident.

We want to give Security Engineer access to our engineers' standard accounts and only provide Huntress Admin access to separate/dedicated privileged accounts. However, this change would necessitate making a privileged account the Point of Contact, and those mailboxes are not well monitored by the engineers (if they even have a mailbox!), so contact from Huntress may be missed during an incident.
