The migration was gated on ownerID.Valid which is only true for PAT/JWT
registrations. Daemon token registrations (the common case for background
daemon restarts) had ownerID as zero, skipping migration entirely.
Fix: use registered.OwnerID (preserved via COALESCE on upsert) instead
of the caller's ownerID. This ensures migration runs even when the daemon
re-registers via daemon token after an upgrade.
