feat(backoffice): amélioration navigation mobile et tablette

- Ajout d'un menu hamburger mobile (MobileNav) avec drawer animé via React Portal (évite le piège du backdrop-filter du header)
- Popin JobsIndicator adaptée mobile : positionnement fixed plein-écran sur petit écran, backdrop semi-transparent
- Navigation tablette (md→lg) : icônes seules avec tooltip natif, labels visibles uniquement sur lg+
