The network probe used community.docker.docker_network_info, whose
get_network() scans GET /networks and returns the first entry whose Name
equals the requested name OR whose Id starts with it, in a list order that
changes between calls. In main run 38038541631 (Zammad#1, swarm) the
central redis overlay got the ID n8nwzb1q39m3u4k7awwwmt6yg, the probe for
the not yet created provider network "n8n" returned it as existing, the
create step was skipped, docker stack deploy attached hermes to the redis
overlay as "n8n", and the oauth2-proxy then reached the password-protected
central redis by its bare host name: "NOAUTH Authentication required".
The same scan can also return the ID-prefix twin of a network that does
exist, so comparing the returned name alone would turn that network into
"missing" and fail the create with "already exists".
Both probes now run `container network ls --filter name=<entity> --format
'{{json .}}'`, whose name filter never matches an ID. The new lookup
network_driver picks the entry named exactly after the entity and returns
its driver, '' when there is none; the drift checks, their messages and the
create steps all read that one entry. No docker module is left in the file,
so its two docker-module-uses-container-cli suppressions go too.
Verified: on the host daemon GET /networks/<id prefix> returns a network of
another name and docker network ls --filter name=<id prefix> returns
nothing. In ansible-playbook against real docker network ls output the
lookup returned the exact network's driver in 20 of 20 probes beside an
ID-prefix twin, an empty driver (create path) for a missing network and for
a name only contained in a sibling, and the drift path for a foreign
driver. Unit tests cover the same cases; with a substring match instead of
the exact name the two sibling cases fail.
