 * Returns the resolved `EoiContext` — the actual data that would be

 * the EOI generate dialog's pre-flight preview so a sales rep can see
 * (and correct) every value before sending the document for signing.
 *
 * No mutation; pure read of denormalized data the EOI builder already
 * computes server-side. Returns 404 if the interest is missing or in
 * another port (the buildEoiContext function throws NotFoundError).
