Stop exposing raw "accountID" values directly in the web UI
Ref T13493. The "AuthAccountView" UI element currently exposes raw account ID values, but I'm trying to make these many-to-one.
This isn't terribly useful as-is, so get rid of it. This element could use a design refresh in general.
Test Plan: Viewed the UI element in "External Accounts".
