Places: /shape/<key>, voices, address newsletter

The landing gesture leads to /shape/{curve.key} - the place page:
what was left there (the relay's /place, playable), leave your voice
(type: voice at value "{key}"), hear from exactly this address
(redoal_watchers, exact key), and the cards. Email leaves the landing
page. A card for iroh through varde. Desks for voices and watchers.
