refactor: simplifier UI server audio users — entrée vide = écoute seule

Supprime la checkbox "Publier audio" et la colonne Mode.
Le comportement est déduit de l'entrée : aucune entrée = écoute seule.
Option "Aucune entrée" ajoutée au select canal d'entrée (comme pour sortie).
publish dérivé de inputChannel !== null dans AudioBridgeManager.
