Reviewed upstream patch (Kludex/python-multipart#267) and audited test fixtures.

Fix correctness: per-state instrumentation across HEADER_FIELD_START / HEADER_FIELD / HEADER_VALUE_START / HEADER_VALUE / HEADER_VALUE_ALMOST_DONE with per-part counter resets at part_begin and boundary continuation. Both attack vectors (excessive headers, oversized header line) covered. Clean MultipartParseError on overflow.

Defaults vs FilaOps traffic: MAX_HEADER_COUNT=8, MAX_HEADER_SIZE=4224 bytes per line. FilaOps upload endpoints (PO documents, quote attachments, customer/order/material imports, settings logos) all use browser-driven multipart with 2-3 headers per part and ~200-byte header lines — comfortable headroom.

Test fixture audit: all 30+ TestClient files={...} call sites generate standard httpx multipart (2 headers per part). No hand-crafted raw multipart bodies. No regressions expected.

CI: all green (FilaOps CI, CodeQL py+js, backend unit/integration tests, PRO Code Guard, GitGuardian, Review Council). The duplicate Review Council FAILURE entry is the known double-fire — dedicated workflow run passed.

Merging to close DoS attack surface across 14 upload endpoints.
