Store waveform peaks inline in audio_versions (JSONB columns) so WaveSurfer
can render the waveform immediately on page load without waiting for audio
decode. Adds a 100-point mini-waveform for version selector thumbnails.
Backend:
- Migration 0006: adds waveform_peaks and waveform_peaks_mini JSONB columns
- Worker generates both resolutions (500-pt full, 100-pt mini) during transcode
and stores them directly in DB — replaces file-based waveform_url approach
- AudioVersionRead schema exposes both fields inline (no extra HTTP round-trip)
- GET /versions/{id}/waveform reads from DB; adds ?resolution=mini support
Frontend:
- audioService.initialize() accepts peaks and calls ws.load(url, Float32Array)
so waveform renders instantly without audio decode
- useWaveform hook threads peaks option through to audioService
- PlayerPanel passes waveform_peaks from the active version to the hook
- New MiniWaveform SVG component (no WaveSurfer) renders mini peaks in the
version selector buttons
Fix: docker-compose.dev.yml now runs alembic upgrade head before starting
the API server, so a fresh volume gets the full schema automatically.

"""Store waveform peaks inline in audio_versions table.

Replaces file-based waveform_url approach with two JSONB columns:
|
|
- waveform_peaks: 500-point peaks for the player (passed directly to WaveSurfer)
|
|
- waveform_peaks_mini: 100-point peaks for library/overview mini-waveform SVG
