Add dynamic lights setting and fix macOS config paths

- Add DynamicLights (0–7) setting mapped to the eu07.ini dynamiclights key,
  exposed as a slider in the Graphics section of Settings.
- Fix config file paths on macOS for eu07.ini, eu07_input-keyboard.ini,
  and userpresets.json to use ~/Library/Application Support/MaSzyna/
  instead of falling through to the Linux XDG path.
