Viewer PDF.js mode livre avec signets, fix hydratation SSR

- Viewer PDF.js mode livre : double page côte à côte, navigation prev/next visuelle et clavier
- Panneau signets (outline) avec tout déplier/replier, highlight du spread courant
- Page 1 = couverture seule, puis paires 2-3, 4-5, etc.
- Navigation clavier : flèches, espace, Home/End
- Redimensionnement auto des canvas au resize
- Fix hydratation SSR : bookData.init() sans await dans ChapterHeader et SongBadges
- BookPdfReader : iframe vers /pdfjs/viewer.html au lieu du viewer natif
- Script postinstall pour copier pdf.min.mjs depuis node_modules
