adventure: a click-through page for every adventurer on the board

Each roster name becomes /adventure/who/{token}. Anyone sees the public sheet —
stats and equipped gear, decoded from the detail_json gogobee now hangs on each
board entry — with a live JSON re-poll so an open tab tracks HP and room as they
move. The signed-in owner sees the same page enriched with their private
inventory, vault, house, and pets, unlocked by an ownership join in the new
player_self_detail table (localpart owns token) — Pete never reverses the
anonymous token to decide it. buyerLocalpart is extracted so the storefront and
the ownership check lowercase the session name the same way.
