papers: drop the poison-lineage vendor from digital-securities

The paper architected investor onboarding around a named KYC vendor from the
satschel lineage — 13 references across five files, including two TikZ nodes and
a \bibitem. That name must not appear in a Hanzo paper.

The architecture is unchanged and is legitimately ours: an external KYC provider
returns a signed attestation by webhook, compliance validates it, the investor
lands in IAM and then on the on-chain ComplianceRegistry. Only the vendor's
identity is removed, so the paper still says exactly what it said.

The \bibitem was never \cite'd — checked before deleting rather than assuming,
since removing a cited key breaks every reference to it. Both TikZ node ids were
renamed with their \draw edges in the same pass, so the diagrams still connect.
Rebuilt: pdflatex clean, 6 bibitems, 165787 bytes.
