This change adds NixOS tests for the MPD (Music Player Daemon) module. Tests include: - Playing audio locally using ALSA directly. - Playing audio locally using PulseAudio (backed by ALSA). - Playing audio from an external client. - Rejecting an external client when it's not explicitly allowed (default configuration). refs #41772
