fix: properly handle kind:7 mark-as-read reactions with event ID to naddr mapping

Restored kind:7 reaction handling with proper implementation:
1. Fetch kind:7 reactions with MARK_AS_READ_EMOJI
2. Extract event IDs from #e tags
3. Fetch the referenced articles (kind:30023)
4. Build mapping of event IDs to nadrs
5. Add marked articles to markedAsReadIds using their nadrs

Now both kind:7 (Nostr articles) and kind:17 (URLs) mark-as-read
reactions are properly tracked and will appear in /me/reads/completed.

Added nip19 import for naddr encoding.
