@remotion/studio: Gracefully handle waveform decode errors

[JonnyBurger]

Audio waveform rendering could take down Studio when decoding fails in the worker. This change makes that path fail gracefully so invalid or undecodable media shows a fallback message instead of crashing the UI.

What changed

• Added a worker error handler in AudioWaveform to surface a recoverable waveform failure state.
• Hardened the waveform worker so unexpected render rejections are reported back as normal errors.
• Updated the user-facing fallback copy to mention decode failures as well as CORS issues.

Notes

• The worker is terminated and cleaned up when it errors so the broken state does not linger.
• This keeps the existing progressive waveform rendering behavior intact for valid media.
