功能：記分板語音改為報比分、發球區、賽末點與獲勝隊伍

摘要：
- 得分播報改為「比分（發球方先報）+ 發球者左右發球區」
- 發球方到賽末點（再得 1 分即獲勝）時，比分後加唸「賽末點」
- 賽末點得分獲勝時，整段改播「<獲勝隊伍> 贏得比賽」
- 發球區左右一律用實際球場方向，取消上方隊伍鏡像；畫面「發球區」顯示同步改為不鏡像，與語音一致

根本原因：
- 現場記分需要即時聽到比分與發球位置，原本只唸「誰得分、誰發球」較不直覺
- 先前發球區對上方隊伍做鏡像，導致語音與實際球場方向相反

影響：
- src/App.tsx：recordPoint 計算發球方比分、發球區、賽末點與獲勝隊伍，重整 voiceAnnouncement 欄位
- src/pages/ScoreboardPage.tsx：語音組字改為「X比Y（賽末點）」「OO左/右邊發球」、獲勝改播「贏得比賽」；發球區顯示移除鏡像；語音設定「播報誰得分」更名「播報比分」

修法：
- 發球方分數先報；賽末點僅在發球方再得 1 分就獲勝時觸發；發球區統一用 getServiceCourt 實際方向
