fix: render compose reply context with card content styling (v2.8.2)

The reply context on the compose page rendered raw Mastodon HTML in a
bare <blockquote>, causing hashtag links to display as block elements
(each on its own line with # separated from the tag name). Wrapping
the content in a <div class="ap-card__content"> applies the same
inline hashtag/mention/invisible-span CSS rules used in the timeline.
