Badges : corrections de lint (E501) et couverture du smoke test

Lignes trop longues détectées par ruff (badges.py, tests) ; ajout de
/badges au smoke test frontend (rendu SSR de chaque écran protégé).

Vérifié dans ce commit : pytest (248 passés), ruff check, alembic
check, tsc --noEmit, eslint, vite build, smoke — tous verts.
