NVIDIA Mission Control autonomous recovery trigger (W13)

Forwards a port replacement / hardware-recovery request to NVIDIA Mission Control's autonomous recovery API (NMC 2.0+). Closed-loop from FIBER risk → NMC ticket → physical action.

Body: {"switch_name":..., "port_name":..., "reason": str (optional), "risk_score": int (optional), "job_ids": [list, optional]}

Behaviour: • Dry-run if FIBER_NMC_URL / FIBER_NMC_TOKEN env vars unset — returns the payload that would be sent and dry_run: true. • Live call sends POST {NMC_URL}/api/v1/recovery/trigger with bearer auth.

Use risk≥80 from the 3-tier engine to drive automatic invocation; viewer or operator role keys can call this — actual execution happens server-side under the FIBER service account scoped to NMC.
