improve: better audio player UI and debugging for bg-bg cards

- Add debug logging to navigation.go to diagnose audio file loading issues
  Prints paths being checked and whether files are found

- Improve AudioPlayer UI for Bulgarian-Bulgarian cards:
  - Add labels showing 'Front' and 'Back' for bg-bg audio buttons
  - Labels only show when audio files are actually loaded
  - Better visual distinction between the two playable audios
  - Reorganized button layout with VBox for cleaner appearance

- Track bg-bg state in AudioPlayer (isBgBg field)
  - Automatically set when back audio file is loaded
  - Used to determine when to show labels

This makes it clearer that Bulgarian-Bulgarian cards have two independently
playable audio outputs, and helps debug why audio isn't being loaded.
