Restaurant owners can now enable/disable AI-translated menu languages (EN/DE/AR/RU/FR) from the account screen, calling the new /restaurants/:id/languages endpoints. Turkish stays as the fixed base language; adding a language triggers a full AI translation pass, removing one just hides it (translations are kept for a fast re-enable).
