Mise à jour capteur bruit: ancien I2C → NSRT MK4 USB

- Nouveau script sound_meter/read.py pour lecture à la demande (JSON)
- launcher.php: appel du script Python au lieu de l'ancien binaire C
- sensors.html: carte USB, suppression boutons start/stop, affichage JSON
- Traductions fr/en: I2C → USB, NSRT MK4
