Taiwan-style single league, custom club logos and localization improvements

This update improves custom leagues and Traditional Chinese support, based on your feedback.

• New custom leagues can use one or two leagues and 4–16 clubs (even numbers).
• Choose “1 league (Taiwan)” for a split season. Half-season winners and annual standings determine the Challenge Series and Taiwan Series, including the applicable one-win advantages. Switch standings between the full season and either half.
• Import or reset PNG/JPG club logos during league creation. Existing games can use club editing in Commissioner Mode.
• Expanded the Traditional Chinese player-name pool. Existing players keep their names.
• Fixed translations in custom setup and postseason screens, tied-club ranking and half-season games-behind displays.

The Taiwan format is a new-game option; existing saves keep their competition format. Half-season ties use head-to-head results, run difference and club order, without extra tiebreak games.
Thanks for your reports and suggestions!
