fix: poll output device name so it updates during playback

The device name was only read on mount and on hover, so it stayed
as "No device" until the user hovered the badges area. Now the
1-second poll also reads get_audio_output_status (cheap in-memory
read) alongside hardware status, keeping the device name current.
