hosts: group cards by node, devices and remote, with a reachability dotHEADmaster

The flat grid mixed Proxmox services with the phone, printers and IoT.
hosts.py now gives every entry a group: the node named in its note's
`node`, its own name when other notes name it as their node (so the node
card heads its section), "Devices" for anything else on a private address,
"Remote" for the rest. The list is sorted node by node, node card first,
and the grid starts a titled section at each group change. Up/Down move by
visual row and keep the column, since rows are no longer a fixed five.

`hosts.py --probe` checks every host at once, about a second for the whole
list, and runs beside the list rather than ahead of it. A host with a port
or url is up only when that port accepts a TCP connect, so a service whose
CT is up and whose daemon is down reads red; anything else gets one ping.
