Create a signature session

Generates an embedded signing URL for the specified document type. Always mints a fresh URL — prior unsigned sessions for the same document are voided afterwards on a best-effort basis. Returns 409 if the document has already been signed, or 422 if the company is not eligible (e.g., a member has an SSN or ITIN on file).
