The contracts CLC requires your borrowers to accept, with a link to each PDF.
Which documents apply depends on your tenant, so read this rather than
hard-coding a list.

Do this before creating a borrower: you serve these documents, the borrower
accepts them, and you report the acceptance with
POST /v1/borrowers/{borrowerId}/signatures,
passing back the contract_type and contract_version you got here.

Requires scope borrower:read, which every key carries.
