Accounts from the header, snapshot-first Spending restore, name ownership grants.

Header buttons always leave the current feature screen; an account with
no remembered nostr identity opens Accounts instead of nothing. Logout
confirms in place. A scan finishing after logout or an account switch no
longer drops the new session into offline mode (stateGeneration guards in
sync + ark). Spending restores from the snapshot first. A migration grant
names the identity that owns an address; its manager may register it
without becoming that identity (names/ownership.js). Browser tests for
account access, profile retry, spending restore, thread reply focus,
custom-emoji reactions and registry ownership.
