examples: ADMIN_BIND collides with SERVER_PORT=8081

public-free and paid-relay both set SERVER_PORT=8081, which is the ADMIN_BIND
default (config.rs). An operator following either example with the admin plane
enabled gets 'Address already in use' at startup and no obvious cause. Moves
ADMIN_BIND rather than SERVER_PORT so the nginx config in the example still
matches.
