Introduces a unified interface for working with PulseAudio and PipeWire audio servers without requiring deep knowledge of either system. Features: - AudioServerUtils factory that auto-detects the running audio server - PipewireUtils: Full support for PipeWire's device/profile/node hierarchy - PulseaudioUtils: Support for PulseAudio sink/source management - Node abstraction representing audio sinks and sources - Methods to list, iterate, set default, and control volume of audio nodes - CLI interface for listing and interactively selecting audio nodes The iterator pattern (iter_sinks/iter_sources) automatically activates profiles before yielding nodes, making them immediately usable.
Comprehensive test coverage for the audio_server_utils module: - NodeTests: Basic Node class instantiation - AudioServerUtilsTests: Factory pattern and server detection - PipewireUtilsTests: PipeWire-specific functionality including pw-dump parsing, device/profile/node handling, and volume control - PulseaudioUtilsTests: PulseAudio-specific functionality including pactl parsing, sink/source management, and volume control

Description
This PR introduces a new utility module in checkbox support to scan and control sources and sinks using both Pipewire and Pulseaudio in a transparent way.
The
mainfunctions explains a bit how to use it, but in general:It's non trivial to control nodes outside of the iteration, especially with Pipewire: Nodes are ephemeral, and there's no identifier that is guaranteed to survive after changing device profile.

Run it as a script, and check if the sink on your machine changes.
NB: there are sinks that are available but not actually usable: your settings panel might not update the displayed value in this case.
