Add USB-C, Ethernet, and PoE interface class certifiers (2.61.0).

Dedicated deterministic engines certify class and connection integrity
(CC1/CC2, Rd 5.1 kΩ, VBUS/GND, SuperSpeed if USB3; 10/100 vs GbE
magnetics; PoE only with evidence). Missing evidence is INSUFFICIENT
or N/A, never invented PoE, SuperSpeed, Z, or I. No FEM, no via IPC.
