171-Feature add autodetection of team if match number is wrong

[RemainingDelta]

Changes

• Adds find_match_by_team_name() in matcherino.py — fuzzy-matches a team name against all bracket entrants and resolves their current match number, with a per-tourney
  in-memory cache so the team list is only built once per session
• Fallback triggers in three cases: non-numeric match input, match number not found in bracket, or team name doesn't match either team in the given match — auto-corrects
  the ticket topic and shows the resolved match embed
• Cache is cleared on !endtourney; no additional API calls since all lookups hit the existing 60s requests_cache

Screenshots

Originally match number is wrong so it searches for the correct team and corrects the match number and team name:
