feat(dashboard): browser signatures management UI

- Ajoute dict_browser_h2 dans /reflists (lecture seule via dict_browser_h2)
- Nouveaux endpoints API :
    GET  /api/browser-signatures/entries — liste browser_h2_signatures
         (fallback dict CSV si migration 06 non appliquée)
    POST /api/browser-signatures/entries — ajout fingerprint + reload dict
    DELETE /api/browser-signatures/entries — suppression + reload dict
- Page /browsers : 2 nouvelles sections
    'Base de signatures H2' — tableau des 10 fingerprints, form d'ajout,
    mode lecture seule automatique si migration 06 non appliquée
    'Règles de scoring browser_matcher.py' — tableau statique des 7 dimensions
    (poids, valeurs par famille, seuils de bypass)
- Integration : browser_h2.csv copié dans user_files au démarrage ClickHouse
