Fix New Person flow: redirect to new cluster, show hero face, detect duplicate names

After moving a face to "New Person", the user is now taken directly to
that cluster's detail page. If it's a single unnamed cluster, the face
is shown prominently at the top. Typing an existing name on the name
form triggers a confirm dialog: OK merges into the existing person's
cluster, Cancel saves as a new separate person with the same name.
