UI polish: amber theme, smooth spectrum, MIDI LED, VU tuning

Browse source 
- Rename section labels: COMPRESSOR → COMPRESSION, AUTO-PAN → PANNING
- Replace spectrum analyzer bars with smooth gapless filled wave
- Use gold (#c59c07) for wave/spectrum strokes and piano roll active keys
- Amber CRT-style patch LCD with dark background and gold dot-matrix text
- Add MIDI signal LED with glow between semi and scale controls
- Reduce VU meter sensitivity (5x → 1.5x) and match amber gradient theme
- Add subtle glow behind section and sub-section boxes
- Fix Compressor.h class name and PluginProcessor include to match
