feat: add English translations and detailed attribution files

- Automatic Bulgarian to English translation for all words
- Save translations to separate _translation.txt files
- Include translations in Anki CSV export
- Add detailed attribution files for audio and images:
  - Audio: model, voice, speed, instructions, processed text
  - Image: model, size, quality, style, full prompt used
- Expand image styles to 42 different options (including superhero comic, yoga, etc.)
- Improve image prompts to strongly avoid text generation
- Fix image overwrite issue - now overwrites existing files instead of failing
