Add person detail page and link people tiles to it

GET /api/people/:id returns a published person's profile, public
roles (current and past), published events they were billed at or
hosted, and public awards, each under the same visibility rules its
own page applies. public_phone is never sent.

PersonDetail renders it at /people/:id, the route personHref already
pointed at. PeopleTiles links a tile with a people id to that page;
an expandable tile keeps its details panel and the panel carries a
"View full profile" link instead.
