The tab was built against a list that only held its entries in memory. Read
them from the VM instead, and send every action to UTMSnapshotService.
Which actions a snapshot offers now follows what the backend can do in the
state the VM is in, so a snapshot that cannot be restored right now says so
by being unavailable rather than by failing afterwards.
qemu-img is only part of the macOS app, so a VM whose snapshots cannot be
managed at all shows the details on their own as before.
