feat: animation temporelle des flux Ğ1

Nouveau mode animation accessible via "▶ Animer" dans le sélecteur de période.
- useAnimation : hook gérant frames, lecture, vitesse, filtrage client
- AnimationPlayer : barre de contrôle (play/pause, slider, ×1/×2/×4)
- Granularité auto : 24 frames/h (24h), 7 frames/jour (7j), ~4 frames/semaine (30j)
- Stats et heatmap mis à jour sur la fenêtre courante, zéro requête réseau supplémentaire
