feat: open all profile links within app instead of external portals

- Update nostrUriResolver to return internal /p/:npub links for npub/nprofile
- Replace external profile links with React Router Link components
- Update ResolvedMention, LargeView, and CardView components
- Convert nprofile to npub before routing
- Keep note/nevent links as external (no internal viewer yet)
