Refactor Windows installer scripts and enhance build process

- Updated farmcontrol-server.nsi to simplify setup file handling by defining APP_SOURCE_DIR and removing unnecessary variables.
- Modified installer.nsh to reference the correct launcher executable path.
- Refactored build-windows-nsis.ps1 to accept APP_DIR instead of individual setup file parameters, streamlining the build process.
- Introduced expand-windows-installer.mjs for handling decompression and extraction of Windows app archives, improving artifact management.
- Enhanced finalize-desktop-artifacts.mjs to integrate the new expansion process and ensure proper cleanup of temporary files.
