Fix RichText prop in Kind9802Renderer to pass event object (#213)

* fix: pass source event to RichText in highlight feed preview

The source event preview in HighlightRenderer was only passing the
content string to RichText, which meant custom emoji tags from the
source event weren't processed. Now passes the source event with
the preview content to enable proper emoji and tag-based rendering.

* refactor: use CSS truncation for highlight source preview

- Pass sourceEvent directly for notes instead of extracting content
- Only create synthetic event with title for articles
- CSS line-clamp-1 and overflow-hidden handle truncation
- Media and event embeds remain disabled
