Broaden custom emoji query to include well-known profile relays

Kind 10030 is a replaceable event that may only exist on relays the
user published to. The default pool (user's NIP-65 relays) may not
have it. Now queries both the default pool AND a broader set of
well-known relays (purplepag.es, relay.nostr.band, etc.) in parallel,
picking the most recent event across both sources.
