Reorganize info modal header with personal touch

Changes:
- Switched order: 'About this CV' now first, then CV title
- Changed format to 'CV 2025 - {JAMR}' (braces only around JAMR)
- Added subtitle 'Built by myself' / 'Construido por mí mismo'
- Adjusted spacing and styling for new hierarchy
- Subtitle is italic, gray, and smaller font size
- More personal and authentic presentation
