fix: handle changed /account/multi/list.json response format

Twitter changed the response format from a list with nested 'user'
objects to {"users": [{user_id, name, screen_name, ...}]} with
minimal fields. Now extracts screen_name from the new format and
fetches the full profile via GraphQL UserByScreenName endpoint.
