The base image never starts a service (closes #16)

build.sh and bin/test used to start valkey-server and ping it to prove it runs;
they now check it with valkey-server --version and valkey-cli --version, so the
ping loop, shutdown, and the cleanup of the Valkey run's log files are gone.
/var/log/valkey and /var/log/nginx keep their package owners and modes, and
nginx -t stays. README states that Valkey, PostgreSQL and nginx are installed
but never run. No package install starts a service: invoke-rc.d already denies
every start, and no ENTRYPOINT or CMD starts one.
