fix: review feedback on vehicleId→actorId rename

- Update stale example values: "veh-456"/"vehicle-456" → "actor-001"
- Rename "Vehicle Wallet Roles" heading → "Actor Roles" in sdk.md
- Fix scripts to import via public SDK alias (createSignedBudgetAuthorization)
  instead of internal dist/protocol/sba.js
