Subject: Add multi-row bar layout with maxbarsperrow config option

When monitoring many servers, bars can become too thin to read. The new
maxbarsperrow setting (default 0 = unlimited) wraps bars into multiple
rows of equal height when the count exceeds the limit. The last row may
have fewer, wider bars filling the full window width.
