Bump version to 1.5.4 for DOCX export fix release

- Enhanced getPandocPath() to check common Windows installation locations
- Improved Pandoc path detection for AppData/Local/Pandoc installation
- Enhanced error reporting with more detailed feedback for export failures
- Added better logging for Pandoc command execution and output
- Fixed issue where DOCX exports would fail silently when Pandoc wasn't in PATH
- Now properly detects Pandoc in standard Windows installation locations
