fix(reader): add explicit PDF.js resource paths and pin foliate-js fork

foliate-js could not locate cmaps and standard_fonts at runtime because
no explicit paths were provided to the PDF.js config. This caused
rendering failures for PDFs using CJK fonts or standard PDF fonts.

Changes:
- Pass cMapUrl and standardFontDataUrl to view.open() in reader.ts
- Pin foliate-js fork to commit 74c317d in package.json for reproducibility
- Update build:ts script to copy cmaps/ and standard_fonts/ to
  web/static/vendor/pdfjs/ during build
