fix(monitor): disk observations follow the disk, and OCI containers keep their address

- The observations of a disk belong to its serial number, not to its
  connector: a replaced disk starts clean, and the badge of the list
  counts what the detail of the disk lists.
- An OCI container is recognised while it is still being installed, so
  an image that carries Docker inside is not offered Docker.
- Links use the IPv4 address of a container and write IPv6 in brackets;
  an answer without an address of its own is read again.
- The Monitor restores, when it starts, the DHCP clients of containers
  that were started from it.
