feat: add Fyne GUI mode with interactive flashcard management

- Add --gui flag to launch interactive GUI mode
- Implement word navigation with prev/next buttons through existing cards
- Add delete functionality to remove unwanted flashcards
- Add fine-grained regeneration (image-only, audio-only, or both)
- Implement audio playback using mpg123 on Linux
- Auto-load first word on startup if cards exist
- Save translation files for navigation persistence
- Use DALL-E 2 with 512x512 images (half size)
- Update audio speed to 0.9 (from 0.8)
- Add comprehensive GUI documentation
