fix: correct directory filter flag in address bar completion

Fix directory filtering in address bar path completion:
- Change QDir::Dirs to QDir::AllDirs to include symbolic links to directories
- Remove Qt::DirectConnection from completion signal to avoid thread safety issues
- Fix code formatting in path comparison condition

This change ensures that:
1. Symbolic links to directories are properly shown in completion list
2. Thread safety is maintained for completion updates
