fix: only show external URLs in Reads if they have reading progress

- External URLs with 0% progress are now filtered out
- External URLs only appear if readingProgress > 0 OR marked as read
- Nostr articles still show even at 0% (bookmarked articles)
- Keeps Reads tab focused on actual reading activity for external links
