fix: allow MPL-2.0, NCSA, CDLA-Permissive-2.0 licenses in deny.toml

Add licenses used by transitive dependencies:
- MPL-2.0: cssparser, lightningcss, parcel_selectors, dtoa-short, option-ext
- NCSA: libfuzzer-sys (via rav1e/ravif/image)
- CDLA-Permissive-2.0: webpki-root-certs, webpki-roots
Remove unused Unicode-DFS-2016 allowance that caused warning.
