fix(lang): redirect par langue reste sur l'hôte courant (.onion compris) + détection langue fiable

Browse source 
- base mailto hote courant via Host header (http pour .onion, https sinon) :
  canonical/hreflang restent sur le domaine actuel, plus de fuite vers le Funnel
- meta refresh rendu relatif et différé à 1.5s pour laisser le JS choisir la langue
- localStorage isolé dans son propre try/catch : la détection navigator s'exécute
  même quand le stockage est bloqué (Tor), plus de Français systématique
