Hand off a Sumsub share token for an external wallet user

External Wallet Access variant of the shared-token handoff: Partner Auth signs the raw body and urId travels in the body, not a header. The first handoff lazily creates the onboarding session; UR copies the applicant, validates the data, and returns the same passed, incomplete, or terminal verdict as the Managed Custody handoff.
