chore(debug): revert TEMP Ford/Volvo diagnostic logging

Diagnosis captured: Ford catCode group.action returns a vehicle-selection
page (30 vehicle.action rows, no group rows) — needs an extra selection
level before groups. Polestar json-model-years returns an HTML landing page,
not JSON — needs a different navigation flow. Both tracked for follow-up.
