fix: set proper mute state for audio/video tracks after reconnection

[coder-with-a-bushido]

Closes #962

How does it fix that?

The methods publishAudioTrack and publishVideoTrack are called on call reconnection here -

client-sdk-flutter/lib/src/participant/local.dart

Lines 560 to 570 in 70d4d1f

	Future<void> rePublishAllTracks() async {
	final tracks = trackPublications.values.toList();
	trackPublications.clear();
	for (LocalTrackPublication track in tracks) {
	if (track.track is LocalAudioTrack) {
	await publishAudioTrack(track.track as LocalAudioTrack);
	} else if (track.track is LocalVideoTrack) {
	await publishVideoTrack(track.track as LocalVideoTrack);
	}
	}
	}

But inside the methods we're not passing the muted state from the old tracks we have. It defaults to false because it's not set in protobuf:

client-sdk-flutter/lib/src/proto/livekit_rtc.pb.dart

Line 1153 in 70d4d1f

if (muted != null) result.muted = muted;

By passing it correctly, this PR fixes the bug in the linked issue.

🐰 A muted state now sticks around,
No more silence lost and found!
Track the truth, don't fake it false,
Reconnect without a cost! 🎙️

lib/src/participant/local.dart (3)

132-142: LGTM! Correct propagation of mute state for audio tracks.

This change ensures that when an audio track is (re)published—particularly during reconnection via rePublishAllTracks()—the track's current muted state is communicated to the server, fixing the issue where the protobuf field defaulted to false.

---

355-367: LGTM! Correct propagation of mute state for video tracks.

Same fix applied consistently to video track publishing. This ensures video track mute state is preserved across reconnections.

---

869-885: No muted field needed here; backup codec inherits mute state from publication.

The AddTrackRequest at line 869 intentionally omits the muted field because it adds a backup codec to an already-published track, not a new publication. The sid field links this request to the existing publication, whose mute state is already managed. Backup codec variants inherit the publication-level mute state, so there's no risk of inconsistent behavior.
