Pull request overview

This PR replaces the legacy AndroidView-based waveform seek bar used for voice messages with a Jetpack Compose implementation, aligning the voice-message UI with the post-ChatKit architecture and reducing reliance on View interop.

Changes:

• Added a new ComposeWaveformSeekBar composable that draws a waveform track and custom thumb.
• Updated VoiceMessage to use the Compose waveform slider instead of WaveformSeekBar + AndroidView, and to shrink waveform data to a fixed bar count.
• Minor import reordering in ChatMessageUi.
