refactor: separate UI translations from CV data

- Created separate ui-en.json and ui-es.json files for UI strings
- Removed 'ui' section from cv-en.json and cv-es.json
- Added LoadUI() function to load UI translations separately
- Updated handlers to load UI data independently from CV data
- Updated template to use .UI instead of .CV.UI

This separation follows proper concerns:
- CV JSON files contain only professional CV content
- UI JSON files contain only application interface strings
- Each can be updated independently without affecting the other
