Makefile: fixed setup_test_to_use_xxx to only clean up the cli containers and not all containers (#837)

* fix(make): scope setup_test_to_use_local_image cleanup to the compose stack

The previous target ran `docker ps -aq | xargs -r docker rm -fv`,
which force-removes EVERY container on the host — not just the kosli
test stack defined in docker-compose.yml. That's a footgun for anyone
running unrelated containers (other projects, dev DBs, sidecar tools)
on the same machine.

`docker compose down -v` only touches the project's own containers
plus its named volumes — exactly what's needed when switching to a
locally-built server image. Same approach already used by
bin/reset-or-start-server.sh.

* fix(make): scope setup_test_to_use_staging_server_image cleanup to the compose stack

Same broad-cleanup footgun as setup_test_to_use_local_image fixed in
the previous commit — `docker ps -aq | xargs -r docker rm -fv` force-
removes EVERY container on the host. Replaced with `docker compose
down -v`, which only touches the project's own compose stack.
