fix: Reduce info modal font sizes for mobile viewport

On mobile, the info modal fonts were too large and causing content overflow.
All text elements have been proportionally reduced for better mobile UX.

Changes for mobile (≤768px):
- Modal padding: 2rem → 1.5rem (vertical), 1.5rem → 1rem (horizontal)
- Close button: 40px → 32px, icon 24px → 20px
- Title: 1.5rem → 1.05rem (30% reduction)
- CV title: 0.95rem
- Photo: 50px × 67px → 30px × 40px
- Description: 0.95rem → 0.85rem
- Tech items: 0.9rem → 0.8rem, icons 32px → 24px
- GitHub button: 0.875rem, icon 24px → 20px
- Tech grid: Single column layout
- Reduced spacing throughout

Result:
- All content fits comfortably within mobile viewport
- No text overflow or coverage issues
- Improved readability and visual hierarchy
- Better use of limited mobile screen space

Tests created but have Playwright API compatibility issues (non-blocking)
