"""Hermes Multi-Provider Account Router: Live Provisioning and E2E Validation Runner.

Strictly follows fail-closed validation rules:
- No artificial 'PASS' or hardcoded booleans.
- Profiles are verified against live APIs/credentials.
- If a profile is unauthenticated, its status is 'AUTH REQUIRED' or 'NOT TESTED'.
