Include Essentia models in repo + optimize CI/CD

Problème: Les modèles Essentia (28 MB) étaient téléchargés à chaque build CI/CD
- Ralentit les builds (~30 secondes de download)
- Consomme bande passante
- Point de défaillance si serveur Essentia down

Solution:
- Commit les 6 modèles dans backend/models/
- Supprime steps "Download Essentia models" du workflow Gitea
- Retire backend/models/*.pb et *.json du .gitignore

Modèles inclus (~28 MB total):
- discogs-effnet-bs64-1.pb (18 MB) - embedding model
- genre_discogs400-discogs-effnet-1.pb (2 MB) - genre classifier
- genre_discogs400-discogs-effnet-1.json (15 KB) - genre metadata
- mtg_jamendo_moodtheme-discogs-effnet-1.pb (2.6 MB) - mood
- mtg_jamendo_instrument-discogs-effnet-1.pb (2.6 MB) - instruments
- mtg_jamendo_genre-discogs-effnet-1.pb (2.7 MB) - genre alt

Bénéfices:
✅ Builds CI/CD plus rapides (~30s gagnées)
✅ Pas de dépendance externe au serveur Essentia
✅ Versioning des modèles avec le code
✅ Repo offline-friendly
