feat(backend): expose GET /api/v1/alerts

Consultation des alertes de consommation, filtrable par site_id et severity a l'identique du contrat GET /alerts de l'API Mock. Reprend le gabarit endpoints -> services -> repositories -> models pose par sites, sur la table alert deja creee par la revision Alembic e6d2026091501. Generalise aussi le garde-fou OpenAPI du 403 (ROUTES_A_ROLE) au-dela du seul tag users, pour que l'ajout d'alerts a la liste des routes protegees par role soit reellement verifie. Closes #59
