Subject: [PATCH] feat: implement resource validation checks for production
 deployment

- Added a new ResourceChecker type to validate system resources including disk space, RAM, and CPU cores.
- Implemented CheckDiskSpace, CheckRAM, and CheckCPU methods to ensure minimum requirements are met for production deployment.
- Integrated resource checks into the ProductionSetup's Phase1CheckPrerequisites method to enhance deployment reliability.
- Updated systemd service generation to log output to specific log files instead of the journal for better log management.
