fix: ensure single directory per card with consistent ID

- Fixed issue where multiple directories were created for the same word
- Added findCardDirectory to check for existing directories before creating new ones
- Updated all file creation functions to reuse existing card directories
- Applied fix to both GUI and CLI code
- Added phonetic fetching to processing counter in generateMaterials
- Now each card gets one directory with all its files
