fix: correct path references in batch_convert_html.sh

The script was using incorrect relative paths after changing to the
scripts/ directory. Fixed:
- Changed initial cd from SCRIPT_DIR/../ to SCRIPT_DIR/../../ to reach project root
- Updated converter script paths from ./converters/ to ../tools/converters/
- Moved directory existence checks before cd to scripts/

Fixes #38
