feat(licenses): add license management and user authentication features

- Introduced a new SQL schema for managing licenses and users, including foreign key relationships.
- Implemented API routes for license validation, activation, and OTP-based user authentication.
- Updated the license creation process to associate licenses with users and handle server IPs.
- Added support for the nanoid package to generate unique license keys.
- Refactored existing code to improve modularity and maintainability, including the separation of license and stripe-related logic into dedicated API routes.
- Enhanced error handling and logging for better debugging and user feedback.
