feat(desktop): move vm-manager in as the vm module

Virsh.qml is unchanged; VmPanel's body becomes the page and the stat row
becomes a Flow, because four stats with 150px bars do not fit a 600px
drawer as one row. The page starts and stops Virsh.sampling, so the 2s
poll runs only while something is looking at it; the lifecycle event
stream still runs always, which is what keeps the tile's dots current.
