feat(frontend): vue /recommendations avec filtre site, focus ?alert= et génération admin
Page derrière authGuard, ouverte à tous les rôles : filtre site (.form-select, présélectionné par ?site=), focus sur une alerte par ?alert= (entier strictement positif, sinon ignoré), et pour les admins un bouton « Générer les recommandations » qui appelle POST /recommendations/generate sur le site filtré, affiche le bilan accordé en nombre et recharge la liste. Route ajoutée dans app.routes.ts, lien « Recommandations » dans la navigation du tableau de bord.
