Fix CSV formatting and encoding issues

- Remove blank lines at top of CSV files using Nunjucks whitespace control
- Add UTF-8 BOM transform for proper French accent encoding in Excel
- Translate content type values in French CSV from English to French:
  - 'Landing Page' → 'Page d'atterrissage'
  - 'Content Page' → 'Page de contenu'
  - 'Link' → 'Lien'

This ensures both English and French CSV exports work correctly with proper encoding and localized content.
