fix(scripts): use powershell instead of pwsh and add DesktopOnly mode

- Replace pwsh with powershell for Windows compatibility
- Add -DesktopOnly flag to skip all external services
- Add automatic port 1420 cleanup before starting
- Improve stop command to kill all related processes
- Update package.json scripts for easier access
