Promtail was not shipping logs due to missing /var/lib/promtail directory
and insufficient permissions (not in adm or systemd-journal groups).
Logs Explorer dashboard queries failed on Loki 3.x because allValue ".*"
is rejected as an empty matcher — changed to ".+" which requires at least
one character. Removed unit filter from main Logs query since varlog
streams lack the unit label.

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.

deploy-observability:
- Discover DNS from UPLINK config instead of hardcoding 8.8.8.8
- Set ipv4.address on OVN NICs (port security drops unknown IPs)
- Install ca-certificates/curl/gnupg before adding Grafana apt repo
- Fix ACL create syntax (--description flag, not key=value)
- Add NIC recovery after ACL changes (NICs go DOWN)
manage-dashboards:
- Rewrite read_manifest() without PyYAML dependency
- Fix ensure_folder() mixing debug output with return value
- Rewrite install payload generation with heredoc + file I/O
- Separate incus file push from Grafana API call
- Fix while-read loops consuming stdin from incus exec (fd3)
Dashboard JSON:
- Add allValue:".*" to all template variables with includeAll
Screenshots:
- Add Playwright screenshots of all 9 Grafana dashboards
