Fix custom emoji rendering in compact view (#51)

Custom emoji were not displaying in compact event previews because
DefaultCompactPreview was passing only content string to RichText,
which strips emoji tag metadata needed for :shortcode: -> URL mapping.

Now passes full event object to preserve emoji tags when rendering
content, while still using plain text rendering for specific titles.

Fixes emoji display in compact rows and reply previews.
