catborise 321749f8fa feat(computes): the Computes list on Bootstrap's cards, badges, bars and menus
- Totals above the list: hosts connected of all, VMs running of all,
  vCPUs given on the CPUs, memory given of the memory of the hosts the
  panel reads, as cards; the connected count is red while a host is
  not.
- A host's name links its overview; its state is a Connected or Not
  connected badge (the dot goes), beside a badge of how the panel
  reaches it (TCP, SSH, TLS, Socket); its address in monospace.
- A VMs column: the host's VMs, linked to its Instances, and how many
  run.
- The vCPUs have a bar like the memory's: running VMs' and shut-off
  VMs' vCPUs against the CPUs, amber over 2:1 and red over 4:1 as the
  ratio is; the overview's vCPU card shares it.
- The three coloured buttons of each row are one menu: Overview, Edit
  connection and Remove from panel (its popper fixed, as the table's
  scrolling box would cut it off).
- The four green add buttons are one "Add host" menu that says what
  each kind of connection is.
- The table is table-hover; a host the panel cannot reach has a
  table-warning row.
