Fix generic npub names: query profile aggregators in parallel in useAuthor

Previously useAuthor only hit the global profile-aggregator relays as a
fallback when the main pool returned zero kind 0 events. On the curated skate
relay many followed users have no profile, so names fell back to genUserName.
Now query the main pool and aggregators (purplepag.es, nostr.band, nos.lol,
damus) in parallel and keep the newest kind 0, so real display names resolve.
