Restored the automation lane and effects sections that were removed during
the Track component refactoring. These sections now render as full-width
rows below each track, spanning across both the controls and waveforms columns.
Changes:
- Created TrackExtensions component for effects section rendering
- Added automation lane rendering in TrackList after each track waveform
- Added placeholder spacers in left controls column to maintain alignment
- Effects section shows collapsible device rack with mini preview when collapsed
- Automation lanes render when track.automation.showAutomation is true
- Import dialog moved to waveform-only rendering mode
The automation and effects sections are now properly unfoldable again.
