Luna Manager maintenance integration
1. Back up your database and portal.
2. Import database/migrate_maintenance_access.sql into your existing MySQL database.
3. Deploy updated portal_reference PHP files and lib/header.php to the existing web root.
4. Log in as administrator, then open Maintenance PINs from the top navigation or a device page.
5. Enroll a registered device using its device_uuid (NOT numeric database ID).
6. Securely provision the generated JSON to the kiosk with provision_maintenance.py.
7. Generate an 8-digit code; the client must have synchronized time.
IMPORTANT: This version stores maintenance secrets in the portal database in plaintext. Protect DB access and backups. Enrollment output exposes a secret; handle it securely.
No automatic remote enrollment is implemented; provisioning still requires a secure device-side step.
