- Migrate print_labels.html and print_lost_labels.html to standalone pages with header and theme toggle - Implement dark/light theme support using data-theme attribute and CSS variables - Add PDF generation endpoints for single and batch label printing - Copy pdf_generator.py from original app with full label formatting (80mm x 105mm) - Fix data response handling to correctly access data.orders from API endpoints - Synchronize table text sizes across both print pages - Remove help buttons from print pages - Database column rename: data_livrara → data_livrare for consistency - Update routes to use correct database column names - Add 7 test orders to database (4 unprinted, 3 printed) - Implement QZ Tray integration with PDF fallback for label printing - All CSS uses theme variables for dark/light mode synchronization
