Secure-Access Troubleshooting Capstone: SSH VTY Fix

Advanced secure-access capstone, run as a fault hunt.

You get symptoms and the required end state — no fault list. Everything is on one device, so the work is knowing which pieces of a management-plane build depend on each other rather than hunting across a topology.
