/**
 * Adds connected-appliance columns to the license_state singleton table.

 * appliance_id       — stable install id generated by the appliance on first boot
 * check_in_url       — URL the daily refresh poller calls (from ~/alga-license /register)
 * appliance_credential — per-appliance bearer credential (for check-in), stored as
 *                        a SHA-256 hex hash so the plaintext never hits the DB.
 * last_checkin_at    — display-only; timestamp of the last successful check-in
