fix: a network, pool or secret a VM needs is not stopped or deleted

Browse source 
Stopping a network cut the running VMs on it off, deleting one or a
secret kept the VMs that name it from starting, and stopping a pool
took the disks of running VMs away, all without a word. Each is now
refused with the VMs (and, for a secret, the pools) that need it:
stopping while a running VM uses it, deleting while a VM's definition
names it. A disk given by its file path does not need its pool's
definition. The API's pool stop is refused the same way.
