feat: enhance port management and server initialization process

- Added a new function to check if a port is in use without terminating processes, improving user experience during server startup.
- Updated the health check function to accept a dynamic port parameter, allowing for flexible server configurations.
- Implemented user prompts for handling port conflicts, enabling users to kill processes, choose different ports, or cancel the operation.
- Enhanced CORS configuration to support localhost and IPv6 addresses, ensuring compatibility across different development environments.
- Refactored the main function to utilize dynamic port assignments for both the web and server applications, improving overall flexibility.
