Release v1.8.1: Streamlined PDF Editor UI

Enhanced PDF Editor user experience with cleaner, more intuitive interface:

✨ UI Improvements:
- Streamlined PDF Editor dialog to show only selected function
- Removed cluttered "all functions at once" display
- Added smooth fade-in animation when showing function-specific sections
- Improved dialog sizing: max-width 600px, max-height 85vh
- Better visual separation with compact section spacing

🎨 Styling Enhancements:
- Added PDF editor-specific CSS classes for better organization
- Enhanced file list styling with better contrast
- Improved remove button styling with danger color
- Complete dark theme support for all PDF editor components
- Better scrolling behavior for long forms

🔧 Technical Improvements:
- Maintained existing show/hide logic (already working correctly)
- Enhanced CSS specificity with .pdf-editor-content and .pdf-editor-body classes
- Added @keyframes fadeIn animation for smooth transitions
- Improved overflow handling for better UX on smaller screens

🌙 Theme Support:
- Full dark mode styling for file lists and entries
- Proper color contrast for all interactive elements
- Consistent styling across all 22 themes

The PDF Editor now provides a clean, focused interface showing only the relevant
controls for each operation (merge, split, compress, rotate, delete, reorder,
watermark, encrypt, decrypt, permissions).
