fix: use per-round match numbering for Round Robin brackets

match_number was a global counter (1-28 for 8 teams), causing badges
to show "Round 2 Match 5" instead of "Round 2 Match 1". Now uses the
per-round loop variable, consistent with SE and DE bracket types.
Safe for multi-stage tournaments since RR advancement uses standings.
