feat(kb-bilibili-metadata): Add UP subscription tracking support

- Enhance _extract_up_async() with subscription tracking:
  - video_count: Number of videos
  - article_count: Number of articles
  - subscription_info: Last video/article for update detection
- Update CLI to support UP subscription queries
- All collection types now support basic_info + subscription status
