vm: show docker containers beside the VMs

Docker.qml mirrors Virsh: the docker CLI, an event stream that runs for the
whole session, and `docker stats --no-stream` on the 2s timer only while the
page is up. Containers are grouped by compose project, since a stack is a
dozen containers that start and stop together; a container outside any
project is a group of one. Verbs are start, stop, restart and resume, by
container id, so no compose file is needed and nothing removes a container.

The event stream is filtered to lifecycle events: health checks emit exec_*
events every few seconds per container, which would make the stream a poll.
It dies with the daemon, so it is retried every 10s.

An inactive Loader keeps its last height and a Column still reserves it, so
collapsing one card left an empty box where its detail had been. Both the
container and VM detail loaders now hide while inactive; the VM one had the
same bug, unseen with a single VM.
