Reduce code font size and spacing in Figure 1

- Change code font from \tiny to \fontsize{6}{7}\selectfont (6pt) for better fit
- Reduce margins: xleftmargin 10pt→5pt, xrightmargin 5pt→3pt
- Reduce spacing: aboveskip/belowskip 8pt→4pt, numbersep 5pt→3pt
- Reduce vspace before subcaptions from 0.3em to 0.15em
- Update numberstyle to match smaller font size
