Add people cluster detail page with face move/merge and hover preview

Each cluster in /admin/people now links to a detail page showing all
faces in a grid. From there you can rename the cluster, move individual
faces to another named person (or spin off a new cluster), or merge the
entire cluster into another. Hovering any face crop shows the original
full photo for context.
