fix: timeline full-width single-column layout + RO language files

- Replace narrow 45%-alternating timeline layout with full-width
  left-edge design: line at left edge, cards use 100% of container
- Cards now span the full 900px content width instead of ~387px
- Removes blank whitespace on both sides that made UX poor
- Applied to all three language versions (ES ID 29, RO ID 69, EN ID 70)
- Add RO locale files for CF7, Polylang, WP Super Cache
