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
