phase: 32_gateway_resolved_target_liveness

Fixture and live stream.conf are byte-identical (modulo header comment). Let me test the parser directly:

     * `predates` — none of the three keys at all (an agent older than 1.2.0, or `--no-proxy`)
     * `no_haproxy` / `no_nginx` — that one config file is absent: `available: false` plus the
