Add playoff round view, game numbers, goal scorer notifications, standings

- Fetch NHL standings and surface league/season game counts in the menu bar
- Prefix regular-season rows with the league-wide game number (from gameId)
- New ROUND section shows each active playoff series (matchup, series score,
  next game number + time) derived from /v1/playoff-bracket; rows always open
  the NHL series page so completed series remain clickable
- Goal notifications include scorer sweater, abbreviated name, and strength
  (PPG/SHG/EN), resolved via /v1/gamecenter/{id}/play-by-play
- Drop the per-team filter submenu and NHLTeam enum
- Regenerate AppIcon with the full 10-size macOS set (alpha preserved) so
  notifications render the app icon correctly; rename the iOS marketing PNG
  to icon-ios-1024.png
- gitignore .claude/ local tooling settings
