feat: fix target audio for all 96 levels and improve layout density

- Enhance targetAudio.js with envelope (ADSR), LFO modulation, effects
  (delay/reverb/distortion), and retrigger patterns for rhythmic sounds
- Fill in target audio configs for 87 levels (worlds 3-12) that had empty
  build arrays, making the "Objetivo" preview button functional everywhere
- Increase base sizes for modules, sidebar, ports, knobs, and typography
  so the UI feels less empty at 100% zoom
