Major improvements to automation and effects bars:
- Both bars now positioned at bottom of waveform (not top)
- Bars are always visible when track is expanded (no show/hide buttons)
- Effects bar at absolute bottom
- Automation bar above effects, dynamically positioned based on effects state
- Removed inner container from effects - direct rendering with EffectDevice
- Removed close buttons (X icons) - bars are permanent
- Effects render directly with gap-3 padding, no TrackExtensions wrapper
- Automation controls preserved (AutomationLane unchanged)
This creates a cleaner, always-accessible interface where users can quickly
expand/collapse automation or effects without toggling visibility.
