feat: team pages with match/tournament history, mobile padding fixes, linked scorers and nations

- Team page: add Tournament Participations (year pills → /tournaments/[year]) and
  Match History (grouped by year, W/D/L badge, opponent, score from team's perspective,
  PSO/AET annotations, each row → match anchor)
- GraphQL: extend matches() query with teamId filter (OR team1_id/team2_id)
- Match card: link team names to /teams/[slug]; fix ET score display — show scoreEt
  as headline for AET matches, scoreFt as footnote; winner determination uses
  scoreP ?? scoreEt ?? scoreFt
- Tournament page: scorer names below each match linked to /players/[name] with
  dotted underline (solid + green on hover)
- Stats page: reduce mobile padding on Goals chart, Top Scorers, Titles, Goals by
  Minute — hide progress bars and trophy emojis on small screens
- Homepage: Golden Boot Race same mobile padding/bar treatment; add slug to match
  team queries
