feat: show detail view for all addressable events in naddr preview

Previously, PreviewAddressPage only handled spellbooks (kind 30777) and
showed errors for other addressable events. Now:

- Spellbooks (kind 30777): Redirect to /:actor/:identifier (existing behavior)
- All other addressable events: Show in EventDetailViewer

This enables previewing any addressable event (long-form articles, live
events, community posts, etc.) via naddr links.

Changes:
- Import EventDetailViewer
- Removed error state for non-spellbook kinds
- Show EventDetailViewer with AddressPointer for all other kinds
- Simplified from 83 lines to 77 lines
