Just made Iris use only the "name" field from profile.

The concept of "username" can be a bit confusing in the context of Nostr, because it's not globally unique, and can be confused with nip05 addresses. "Nickname" or "alias" would be better, but probably not necessary.

Also the UI is simpler and prettier when you don't display a "username" separately.
