fix(client): warn about dangling audio bindings only for published audio tracks (#2183)

### 💡 Overview
This PR fixes an issue where the audio bindings watchdog reported
dangling audio bindings even after the track had been unpublished.

## Summary by CodeRabbit

* **Bug Fixes**
* Improved accuracy of audio binding detection by aligning warnings with
actual published audio tracks rather than the mere presence of audio
streams.

* **Tests**
* Added test coverage for the updated audio binding detection behavior.
