refactor(nip-66): improve feed UI with clickable titles and simplified layout

- Add ClickableEventTitle to relay discovery feed items for opening detail view
- Remove "Monitoring" label from relay monitor feed items for cleaner layout
- Remove unused imports (RelayLink, Label, Activity) from feed renderers
- Maintain existing Label and NIPBadge usage in detail renderers
