Campaign CTA buttons link to /order/<slug>?dot=1234567. Add a fast local-only
GET /api/v1/dot/census endpoint (vs the heavy 12s live /dot/lookup) and a ?dot=
branch in the Wizard that seeds intake_data from the carrier's cached FMCSA
census record (name, email, base state, city/street/zip, power units). The
existing StateTrucking step already prefills its inputs from intake_data, so the
form now shows up pre-populated. Best-effort: only fills empty fields, never
blocks the form, never overwrites visitor input.
