fix: remove CV content font size reduction in responsive mode

Only reduce sidebar font sizes in responsive mode (1024-1280px), not the main CV content.
- Keep: sidebar-title and sidebar-content font reductions
- Remove: experience-item and project-item font size reductions
- Main CV content now maintains normal font size in all screen sizes
