Refactor license and permission management, add services

Renamed licenceRepository.js to licenseRepository.js and updated its API to use status instead of userId for licenses. Moved permission checking logic from userRepository to permissionsRepository. Added new service layers for license, permissions, and user management, implementing error handling and business logic. Removed the old register.js service and cleaned up test.js. Updated database schema to remove userId from licenses.
