功能：自動選隊排除「那個」、選隊面板顯示每人今日場次

摘要：
- 記分板「自動選擇」時排除名字為「那個」的球員，手動仍可勾選
- 結算完成（上傳或不上傳）時幫上場 4 人各記一場，輪空不計
- 選球員面板每位球員名字旁顯示「今日 N 場」徽章

根本原因：
- 名單裡的「那個」是佔位用名字，自動選擇會把它當一般球員排進場
- 現場排下一場時沒有依據看誰打得多、誰打得少，容易分配不均

影響：
- src/App.tsx：新增 playCounts state 與 localStorage 持久化（跨日自動歸零）、recordPlayedMatch() 於 skipUpload 與 uploadSettledMatch 成功時計數、傳 playCounts 給記分板
- src/pages/ScoreboardPage.tsx：新增 AUTO_PICK_EXCLUDED_NAMES 常數過濾自動選擇、選隊 modal 每列加「今日 N 場」徽章
- src/App.css：徽章樣式與選項改三欄 grid（含手機版縮小字級）

修法：
- 自動選擇先以排除名單過濾 selectablePlayers 再洗牌取 4 位
- 場次以 {date, counts} 存 localStorage，載入時日期非當天即歸零
- 計數以 activeMatchup 兩隊為準，isPlaceholder 的輪空欄位跳過
