Add ElementType.LOGO to the list of visual element types in pdf_generator_service.py so that logo images are properly rendered in Direct track PDF output. Root cause: edit2.pdf logo element (type="logo") was not being categorized as an image element, so it was skipped during PDF rendering. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
