feat: add audio device switcher to bar

[flathead]

Adds a bar button for switching audio output/input devices with a popup selector.

What was added

New file

modules/bar/AudioDeviceSwitcher.qml -- bar button that:

• Shows a dynamic icon based on the current default sink type
• Opens a popup with Output and Input sections listing available devices
• Clicking a device sets it as the default sink/source
• Supports headset battery display (ArctisManager D-Bus) when a headset-type sink is active
• Filters out devices listed in the exclusion config

Device type detection

Icons are assigned dynamically from PipeWire node properties, not hardcoded names:

Type	Icon	Detection
HDMI/DP	speakerHigh	device.profile.name contains hdmi or displayport
Headphones/USB	headphones	device.bus is usb or bluetooth, or headset/headphone profile
Audio processor	faders	node.virtual=true or application.id matches easyeffects, carla, jamesdsp, pulseeffects
Virtual routed sink	inherits from driver	node.driver-id traced to real device, classified by its properties
Speakers	speaker	PCI analog, fallback
Microphone	mic	any source

Settings integration

config/Config.qml -- added showAudioDeviceSwitcher (bool, default true) and excludedAudioSinks (string list, default empty) to the bar adapter.

modules/widgets/dashboard/controls/ShellPanel.qml -- added to Bar section:

• Toggle: "Show Audio Device Switcher"
• Chip selector: "Hidden Audio Devices" with clickable chips for all current audio devices. Click to exclude, click again to restore. Follows the same pattern as the Screen selector.

modules/widgets/dashboard/controls/SettingsIndex.qml -- added search entries for "Audio Device Switcher" and "Excluded Audio Sinks".

Modified files

modules/bar/BarContent.qml -- added AudioDeviceSwitcher via Loader in both horizontal and vertical layouts, between ControlsButton and BatteryIndicator. Visibility controlled by Config.bar.showAudioDeviceSwitcher.
