Enhance deployment system with retry functionality and improved UX

Major Improvements:
- Added retry deployment buttons in machine list for failed deployments
- Added retry button in SSH console modal footer for enhanced UX
- Enhanced deployment process with comprehensive cleanup of existing services
- Improved binary installation with password-based sudo authentication
- Updated configuration generation to include all required sections (agent, ai, network, security)
- Fixed deployment verification and error handling

Security Enhancements:
- Enhanced verifiedStopExistingServices with thorough cleanup process
- Improved binary copying with proper sudo authentication
- Added comprehensive configuration validation

UX Improvements:
- Users can retry deployments without re-running machine discovery
- Retry buttons available from both machine list and console modal
- Real-time deployment progress with detailed console output
- Clear error states with actionable retry options

Technical Changes:
- Modified ServiceDeployment.tsx with retry button components
- Enhanced api/setup_manager.go with improved deployment functions
- Updated main.go with command line argument support (--config, --setup)
- Added comprehensive zero-trust security validation system
