feat: related content and featured cross-content sidebar widgets

- Add excludeId arg to videos and articles GraphQL resolvers
- Add excludeId + featured params to getVideos/getArticles services
- Video page: fetch related videos by tag + featured article in parallel
- Article page: fetch related articles by category + featured video in parallel
- Implement sidebar widgets with thumbnails, metadata, hover interactions
- Add videos.related and magazine.related i18n keys
- Seed dummy articles (spotlight, interview, psychology) and videos with
  overlapping tags for testing related content
