linux: improve conversation detect logging (#302)

Browse Source 
media: correct AirPods conversational awareness state handling

Fix incorrect detection of conversational awareness events. The previous
implementation treated all non-0x01 packets as "disabled", which caused
wrong behavior when the user manually enabled/disabled the feature or when
voice-end events were received.

Adds full decoding for packet types:
 - 0x01 → voice detected
 - 0x06/others → voice ended
 - 0x08 → feature disabled
 - 0x09 → feature enabled
