功能：首頁日期預設當天、記分板語音改為報比分與發球區

摘要：
- 首頁「指定日期」每次進入都預設為當天
- 記分板語音得分播報改為「比分（發球方先）+ 發球者左右發球區」，賽末點獲勝時整段改播「贏得比賽」

根本原因：
- 日期原本從 localStorage 讀上次選的值，重開會停在舊日期
- 語音原本只唸「誰得分、誰發球」，現場較不直覺，球敘想聽到即時比分與發球位置

影響：
- src/App.tsx：targetDate 改為直接用當天、移除日期的 localStorage 記憶；recordPoint 算出發球方比分與發球區，重整 voiceAnnouncement 欄位
- src/pages/ScoreboardPage.tsx：語音組字改為「X比Y」「OO左/右邊發球」，獲勝時改播「贏得比賽」；語音設定「播報誰得分」更名「播報比分」

修法：
- 發球方分數先報；上方（左側）隊伍發球區做左右鏡像以對齊畫面，下方隊伍不鏡像
