Bouton PDF par chapitre, badges morceaux améliorés, PDF configurable admin, git sync admin→prod

- Bouton PDF blanc par chapitre avec numéro de page (ChapterHeader)
- Badges morceaux plus visibles (bordure, poids, hover) dans ChapterHeader et SongBadges
- PDF viewer : page cible + panneau signets ouverts par défaut (BookPdfReader)
- Config YAML : pdfFile dans book, chapterPages pour le mapping chapitre→page
- Admin book : section PDF du livre avec chemin éditable et sauvegarde
- Git sync automatique : chaque sauvegarde admin commit+push en prod (ADMIN_GIT_SYNC=true)
- Docker : git installé en prod, volumes pour .git/site/content/public
