feat: add bilingual support to info modal

- Added 'ui' section to cv-en.json and cv-es.json with modal translations
- Updated Go models to include UI, InfoModal, and TechStack structs
- Modified template to use JSON data instead of inline if/else statements
- Used template.HTML for Description field to allow HTML rendering
- Modal now fully supports English and Spanish translations

Translations include:
- Modal title
- Description text
- Tech stack labels (HTML5 Semántico vs Semantic HTML5, etc.)
- View source button text
