[ISSUE-8] Redesign life counter page with responsive layout and card backgrounds

Changements détaillés:
- Suppression du formulaire de configuration initiale, démarrage direct avec 2 joueurs
- Implémentation d'une grille responsive (2-8 joueurs, 1-4 colonnes selon l'écran)
- Ajout de la configuration dynamique du nombre de joueurs avec mise à jour instantanée
- Création de fonds personnalisables utilisant les illustrations de cartes Scryfall
- Intégration d'une modale de recherche de cartes par nom

Détails techniques:
- Nouveaux composants: PlayerLifeCounter (87 lignes), CardSearchModal (118 lignes)
- Réécriture complète de LifeCounter (209 lignes)
- Design mobile-first avec breakpoints Tailwind (sm, md, lg)
- TypeScript avec typage complet
- Intégration avec le service Scryfall API existant
- Fonctionnalités: édition des noms, vie de départ (20/30/40), reset global

Tests: Build réussi, pas d'erreurs de linting

Resolves: #8
