fix: ui redesign bugs

[isekovanic]

🎯 Goal

This PR restores a few message and audio UX behaviours that regressed from develop. It brings thread-list draft previews back, moves message timestamps into the footer next to status, stops audio from auto-resuming after seek in both message attachments and composer previews, and slightly tightens the voice recording autosend path.

Included changes:

• Restore thread draft previews in ThreadListItem
• Move MessageTimestamp out of MessageStatus and render it in MessageFooter
• Stop autoplay after seeking in AudioAttachment and AudioRecordingPreview
• Reduce voice-recording autosend overhead in useAudioRecorder
• Add the thread-list draft preview theming/context support and update the related thread snapshot/test coverage
