ci: Windows-Strecke - VM-Start/Stop-Jobs + desktop_windows (Issue #5)

start/stop_windows_vm steuern die On-Demand-Build-VM vom Linux-Runner aus
(Docker-Socket). desktop_windows (tags: windows, manuell, unsigniert/nsis)
uebersetzt den x64-Pfad des Upstream-Workflows: frozen-lockfile, webapp +
axion-config vor dem asar, VS-DevShell + build:native mit MSVC-Target.
Wartet in der Queue bis der Windows-Runner (lab-windows-1) online ist.
