fix(ui): use fixed width classes instead of w-full for diagram sizing

SUMMARY:
Fixed diagram sizing issue by replacing w-full with fixed width classes.
Diagram was taking up full screen due to w-full overriding max-width constraints.

CHANGES:
- Removed: w-full max-w-[96px] sm:max-w-[128px] lg:max-w-[160px]
- Added: w-24 sm:w-32 lg:w-40 (fixed widths)

SIZING:
- Mobile: w-24 = 96px (6rem)
- Tablet: sm:w-32 = 128px (8rem)
- Desktop: lg:w-40 = 160px (10rem)

This ensures the diagram is properly constrained to 25% of original size
across all viewports without being overridden by w-full.
