feat(frontend): composant ev-icon en SVG inline pour les types d'alerte
Cinq tracés (spike, threshold, anomaly, outage, sensor) dessinés en trait sur currentColor, dimensionnés par font-size comme ev-brand. Décoratif par défaut (aria-hidden), rôle image et libellé accessible quand `label` est fourni. Aucune bibliothèque : la CSP du reverse proxy interdit les scripts tiers, pas le SVG inline.
