fix: link naddr articles internally instead of to njump

- Articles (naddr) now link to /a/{naddr} route (internal)
- Other nostr identifiers still link to njump.me (external)
- Improved article labels to show identifier instead of generic text
- Better UX: clicking article references opens them in-app
