mana-ai's /metrics endpoint is no longer exposed on Mini's
192.168.178.131:3067 (service moved to GPU-Box, no public /metrics
tunnel since the endpoint is internal). The blackbox-api job
already probes mana-ai.mana.how/health for liveness, which gives
us up/down without needing the metrics scrape.
Status-page is now 58/58 UP after VM rolled past the stale 3067
samples.
