Onboarding: fix the crash after a name claim/migration; keep a login-owned name through signer resume.

"Something broke" right after a coinos.io migration completed: the spend
step advances past the avatar ask by calling nextAfterAvatar(), which was
a const declared further down the same function — a temporal-dead-zone
throw for any profile that already had a picture. Now a hoisted function.

Also, the claimed-name ownership check only counted the LIVE login signer.
A bunker/Google login resumes seconds after load, so for that window a
name owned by the login identity (every migrated coinos.io name) looked
foreign, was dropped, and the wallet key's npub-shaped default took its
place — the address visibly flipped from [email protected] to npub…@coinos.io.
The stored login pubkey now counts as ours too.
