feat: Enhanced bulk import, archive functionality, and export improvements

## Bulk Import Enhancements
- Added support for three flexible batch file formats:
  - `BULGARIAN = ENGLISH` - Both provided, no translation needed
  - `= ENGLISH` - Only English provided, auto-translated to Bulgarian
  - `BULGARIAN` - Only Bulgarian provided, auto-translated to English
- Implemented smart file checking to skip already processed words
- Check all required files (word.txt, translation.txt, phonetic.txt, audio/image files and their attribution/metadata)
- Added batch processing summary with statistics

## Archive Functionality
- Renamed --clear flag to --archive for clarity
- Archive cards directory to ~/.local/state/totalrecall/archive/cards-TIMESTAMP
- Added archive button to GUI toolbar with folder icon
- Archive confirmation dialog supports keyboard shortcuts (y/n/c/ESC)

## Export Improvements
- Anki exports now show full file path in output
- Changed default export location to home directory (~) for both CLI and GUI
- Auto-adjust image size to 1024x1024 when DALL-E 3 is selected

## Other Improvements
- Added TranslateEnglishToBulgarian method for reverse translation
- Enhanced batch processing with better error handling and progress reporting
- Improved file integrity checking for complete word processing
