checker: join Hdr.Name to apex in preferRRName
happyDomain encodes service-embedded record owners relative to the zone apex, so returning the trimmed Hdr.Name as the FQDN owner left relative names like "_465._tcp" leaking into pointer dedup keys and discovery entries. Join with apex unless the name is already suffix-anchored.
