feat: add custom image prompt support and keyboard shortcuts

- Add text area next to image display for custom image generation prompts
- Users can specify their own prompts or leave empty for auto-generation
- Display the used prompt in the text area after generation
- Load prompts from attribution files when navigating to existing cards
- Add keyboard shortcuts for all GUI buttons:
  - G: Generate, N: New Word, I: Regenerate Image, A: Regenerate Audio
  - R: Regenerate All, D: Delete, P: Play audio
  - Left/Right arrows: Navigate between words
  - Y/N: Confirm/cancel delete dialog
- Update UI layout with equal 50/50 split between image and prompt
- Enable text wrapping in prompt text area
- Add 25% chance to ask OpenAI for creative photo style suggestions
- Fix concurrent processing to properly use custom prompts
