Fix inconsistent match counting in log search

Use dataset.logContent instead of textContent for counting search
matches in getMatchCount(). This aligns the counting logic with
matchesSearch() which uses the same data attribute for filtering
visibility, ensuring the displayed match count accurately reflects
the number of visible/hidden lines.
