在庫管理機能 Phase 1 実装（apps/materials + フロントエンド）
Backend: - apps/materials 新規作成（Material, FertilizerProfile, PesticideProfile, StockTransaction） - 資材マスタ CRUD API（/api/materials/materials/） - 入出庫履歴 API（/api/materials/stock-transactions/） - 在庫集計 API（/api/materials/stock-summary/） - 既存 Fertilizer に material OneToOneField 追加（0005マイグレーション、データ移行込み） Frontend: - /materials: 在庫一覧画面（タブフィルタ、履歴展開、入出庫モーダル） - /materials/masters: 資材マスタ管理（肥料/農薬/その他タブ、インライン編集） - Navbar に「在庫管理」メニュー追加 - Material/StockTransaction/StockSummary 型定義追加 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
