Remove batch file creation to reduce AV false positives

- Refactored all process execution to use direct exe calls
- Added ExecuteExeAsync method for direct process execution
- Removed dynamic .bat file creation that triggered Wacatac detection
- All commands now run ControlMyMonitor.exe directly with arguments
