feat: add status and update callback URL for domain reservations

Add status tracking and update callback handling for domain reservations:

- Add status enum to ReserveDomainInvoice (pending, paid, cancelled, failed)
- Add status column to reserve_domain_invoices table with default 'pending'
- Update ONE_OFF_CUSTOMER_URL to include callback path
- Add callback route for EIS billing system
- Update database structure for new status column

This change enables tracking reservation payment status and proper callback
handling for the business registry domain reservation process.
