refactor: simplify NIP-43 renderers to follow codebase patterns

- Use PubkeyListPreview in RelayMembersRenderer feed view (shows actual
  users instead of just count, matching FollowSetRenderer pattern)
- Remove redundant icon props from detail renderers (PubkeyListFull
  has sensible defaults)
- Simplify variable naming and reduce comments
- No functional changes, just cleaner code
