Layout panel wired, section visibility, preset management improvements

- Wire all 5 Layout panel section toggles (Preset Browser, Big Title, Fader Row, Toggle Row, Transport Row)
- Replace checkboxes with clickable title buttons (highlighted=visible, dimmed=hidden)
- Move Big Title inside fader container, between Hide Params button and fader strips
- Wrap transport/fader/toggle rows in container widgets for setVisible support
- Reposition separator between preset browser and mixer row
- Open Layout panel by default on launch
- Add Duplicate preset button (auto-generates new UUID)
- Add Rename preset button
- Swap preset browser label and show-hide button order
- Persist section visibility state per preset under new 'sections' key
