Replace incorrect Prometheus queries across 4 dashboard JSON files:
- incus_uptime_seconds → incus_cpu_effective_total for template vars and counts
- incus_memory_RSS_bytes → incus_memory_Active_bytes (RSS only reports for VMs)
- Uptime panel → Processes panel using incus_procs_total
- Remove wrong instance filter from network deep dive instance panels
- Fix Loki data directory permissions in deploy-observability
Add viewport screenshots of all 9 Grafana dashboards and embed them in
the observability guide with captions and updated descriptions.
