prose: review, fix, and consolidate infrastructure contracts

- DELETE infrastructure-monitoring.prose.md (redundant — proxmox-monitor already deployed this)
- FIX infrastructure-control.prose.md: remove /grafana/ nginx route (reverted Jul 2, broke gpu-fleet)
- FIX infrastructure-update.prose.md: wrong CT IDs (122→112 Tanko, 123→114 Mumuni, .19→storepve Zulip)
- FIX infrastructure-update.prose.md: Strix Halo :8080→router health check (firewalled to .116 only)
- FIX proxmox-monitor.prose.md: stale /grafana/ URLs→:3001 (post-revert cleanup)
- ADD disk-gc-threat-response.prose.md: verified run (2026-07-04, reclaimed 35.67GB from kagentz)
- ADD infrastructure-update.prose.md, pi-approval-architecture.prose.md, zulip-approval-fix.prose.md, zulip-self-heal.prose.md
- UPDATE hermes-config, litellm-health/self-heal, pm2-self-heal, zulip-* contracts
- ADD runs/20260704-005804-51f9a9 (disk-gc-threat-response run artifacts)

All contracts verified against live PVE API, nginx config, and firewall state.
