* fix(pdf): resolve standard fonts from pdfjs package root
Resolve PDF.js standard fonts via pdfjs-dist/package.json instead of a
relative ../../node_modules path so the fallback renderer does not depend
on emitted dist chunk layout.
Add focused regression coverage that asserts the forwarded
standardFontDataUrl matches the installed pdfjs-dist package root and
exists on disk.
* fix(pdf): resolve pdfjs standard fonts from package root
* fix(pdf): use PDF.js font URL separator
