fix(subscriber): disk fallback reads status.json's status, not the dict

read_logged_status() returns the status.json dict; _check_disk_fallback
compared that dict with the terminal status strings, so a terminal status
recorded only in the audit log was never recognised (Issue #57, comment 5).
The dispatch-token and attempt checks are unchanged.
