Refactoring complet : contenu livre, config unique, routes, admin et light mode

- Source unique : supprime app/data/librodrome.config.yml, renomme site/ en bookplayer.config.yml
- Morceaux : renommés avec slugs lisibles, fichiers audio renommés, inversion ch2↔ch3 corrigée
- Chapitres : 11 fichiers .md réécrits avec le vrai contenu du livre (synthèse fidèle du PDF)
- Routes : /lire → /modele-eco, /ecouter → /en-musique, redirections 301
- Admin chapitres : champs structurés (titre, description, temps lecture), compteur mots
- Éditeur markdown : mode split, plein écran, support Tab, meilleur rendu aperçu
- Admin morceaux : drag & drop, ajout/suppression, gestion playlist
- Light mode : palettes printemps/été plus saturées et contrastées, teintes primary
- Raccourcis clavier player : espace, flèches gauche/droite
- Paroles : toggle supprimé, toujours visibles et scrollables
- Nouvelles pages : autonomie, evenement
