Major UX improvement inspired by Ableton Live's device view:
- Effects section now appears below the waveform in the track lane
- Toggle button in control panel shows/hides the effects area
- Gives much more horizontal space for device rack
- Effects section spans full width of track (control panel + waveform)
- Clean separation between track controls and effects
- Header with device count, add button, and close button
Layout changes:
- Track structure changed from horizontal to vertical flex
- Top row contains control panel + waveform (fixed height)
- Bottom section contains collapsible effects area (when shown)
- Effects hidden by default, toggled via "Devices" button
- When collapsed, track doesn't show effects section
This provides a cleaner workflow where users can focus on mixing
when effects are hidden, then expand to full device view when needed.
