Lists tracing documents attached to POs and SOs that reference a style. Scoped to the caller's company via style ownership + the caller's own order books. Cross-company docs surface via the supply-chain tracing_link — this is by design (buyer sees supplier-uploaded docs and vice versa). Response is aggregated by (file, document type): a single file with heterogeneous document types yields one entry per type. orderList includes both purchase and sales orders, discriminated by the orderType field. Archived (is_removed) documents are excluded by default; only returned when isArchived=true. Returns 404 (code: style_not_found) if the style is unknown or belongs to another company.
