Add Windows 7 deploy bundle pipeline

Self-contained zip (dist/avtoambor-deploy.zip) for end users on Windows 7:
double-click install.bat to install Node 16, then start.bat to launch the
server. start.bat self-relaunches minimized so the console window stays out
of the way. Node is pinned to 16.x and several deps downgraded for Win7
compatibility; the unsupported View Transitions hook is dropped from the
root layout. make bundle wraps scripts/make-bundle.sh.
