fix(frontend): translate status badge labels via i18n helpers

StatusBadge and SimulationStatusBadge now call engagementStatusLabel() /
simulationStatusLabel() from @/i18n/status.ts instead of hardcoded English
strings. Tests updated to expect French labels (Planifié/Actif/Clôturé,
En attente/En cours/Révision requise/Terminé).
