fix: presale benchmark missing args + security audit advisory cleanup

- Fix refund_cancelled_presale benchmark: add missing start_index and
  batch_size arguments (0, 100) to match the 3-param extrinsic signature
- Remove 3 stale RUSTSEC advisories from deny.toml and security-audit.yml
  (RUSTSEC-2023-0071, RUSTSEC-2025-0055, RUSTSEC-2026-0002 no longer in deps)
- Add RUSTSEC-2026-0049 (rustls-webpki) to ignore lists (upstream kube/jsonrpsee
  haven't released compatible versions yet)
