refactor(relays): split the public-chat purpose into the five protocols it held

Browse Source 
PUBLIC_CHATS was a catch-all carrying NIP-28 chats, NIP-29 relay groups,
ephemeral chats, geohash chats and live-stream chat under one row labelled
with the NIP-29 name — so the subscription screen could not say where any
of them came from, and the label was wrong for four fifths of what it
counted.

Each is now its own purpose with its own label and explainer. Geohash
cells carry their id too, so location chats list one row per cell and
render as a place name instead of a single opaque group.
