refactor: enhance init.sh and server startup error handling

Browse Source 
- Refactored init.sh to introduce a reusable function for killing processes on specified ports, improving code clarity and maintainability.
- Added a cleanup function to ensure proper resource management on exit.
- Updated server startup logic in index.ts to handle port conflicts gracefully, providing clear error messages and suggestions for resolution.
- Improved logging for server status and health checks during initialization.
