Add a simple, single-file docker-compose for the control-plane/dashboard/prober host

The existing deploy/docker/docker-compose.yml (+ override/prod, Compose
profiles) is flexible but requires understanding profiles and file
layering. For a server that only ever runs these three fixed roles
against a real OpenStack (VK Cloud) deployment, rxprod-compose/ adds a
single flat docker-compose.yml with no profiles — control-api,
admin-dashboard and prober wired together directly, both ports published
on the host (control-api needs to be reachable by validator-agent running
separately on real cloud VMs). OpenStack credentials and the prober's
site_id come from a local .env (gitignored; .env.example is the
template).
