1. Timeout fix for pool alias (syslog-auto):
- Single-host aliases (gpu-dense, gpu-vision, strix-moe): 30s timeout
- Pool alias (syslog-auto): 60s timeout, retry once on 000 before failing
- Cold first request to pool alias can take ~13s; 10s was too short
2. Remove DEBUG prints from output:
- Removed 'DEBUG: keylen=...' and 'DEBUG: response=...' lines
- These leaked key inventory to status logs
- Success output now shows only counts (e.g., 'Admin Key List: 10 keys')
Implements all 11 checks from litellm-health contract:
- Liveliness, Containers, Prometheus, Grafana health probes
- Model probes for gpu-dense, gpu-vision, strix-moe, syslog-auto
- Admin API key list (10 keys), GitHub status, Docker Stats metrics
Fixed quoting for SSH commands and response parsing (dict with 'keys' field).
Backend edge uses internal IP 192.168.68.116, not public URL.
Docker Stats fetched from CT 116 host itself (127.0.0.1:9324/metrics).
All 11 checks passing consistently.
