確定取消 API	✅ is_confirmed: false, confirmed_at: null
USE トランザクション削除	✅ current_stock が 27.5→32 に復帰
引当再作成	✅ reserved_stock = 5.000 に復帰
追加した変更:

stock_service.py:81-93 — unconfirm_spreading(): USE削除→確定フラグリセット→引当再作成
fertilizer/views.py — unconfirm アクション（POST /api/fertilizer/plans/{id}/unconfirm/）
fertilizer/page.tsx — 一覧に「確定取消」ボタン（確定済み計画のみ表示）
FertilizerEditPage.tsx — 編集画面ヘッダーに「確定取消」ボタン + 在庫情報再取得
