GitLab

Bring the contact, who is currently signed in, to the top.
If no user is signed in, we can still synthesize a contact
entry with the available information (best-effort).

Note: This CL uses a blue star to mark the record that was
moved/synthesized. This should be considered a placeholder.
Will work with UX to flesh out how it should look like.
