- Updated Dockerfile to use Node 22.6.0-alpine for improved performance and security.
- Modified package.json to enhance the 'start:dev' script with debugging options.
- Added new launch configuration in VSCode for attaching to Node processes by PID.
- Cleaned up settings.json by removing unused configurations.
- Refactored main.ts to simplify the bootstrap process.
- Enhanced logging in OrderSchema and ScheduleSchema for better traceability of operations.
