refactor(console): a console's URL names its compute and VM

The console page is /console/<compute>/<uuid>/ with the view and display
options in the query. It was /console/?token=<compute>-<uuid>, a "token"
that was only the VM's address, parsed alongside a signed token that no
link ever sent. The list's console button takes the VM's UUID from the
database instead of asking libvirt for each row, and no longer defines a
global function per row.
