/**
 * Deal-lineage ownership on project attach (GHSA-wrg5, codex round 3).
 *
 * requireProjectOwnership vets only the DESTINATION project. Attaching a quote
 * cascades through linkDealToProject, which re-points every event the deal
 * produced into that project — so an editor could create an empty project of
 * their own, attach another admin's quote, and pull that admin's events (and
 * the invoices, emails and gallery that roll up with them) into a project they
 * own and can read via /:id/overview. An unassigned project offered no
 * resistance either: it ADOPTS the deal's customer rather than rejecting it.
