docs(openspec): archive fingerprint-token-auth after the production pass

The wizard's a2loft calls now authenticate with the session token and carry no
OTP. Field pass in production: the lookup and both fingerprint saves succeeded
with no OTP, so task 3.2 is done. Merged the fingerprint-wizard and tools-app
deltas into the main specs and archived the change.
