fix(tui): restore blockquote styling after inline links

The quoteInlineStyleContext used an empty stylePrefix, so after inline
elements (links, bold, code) closed their ANSI codes inside a blockquote,
the quote color was not re-applied. Text following a link rendered in
default foreground instead of the quote theme color.
