feat(chat,board): file/image attachments on chat, board threads and comments
チャット・掲示板(スレッド/コメント)へファイル/画像添付を追加。 - lib/db/migrations/002_attachments.sql: attachments テーブル + file_assets.source 列 - repositories/AttachmentRepository + services/AttachmentService: 添付紐付け(プロジェクト/アップロード者チェック) - FileStorageService.uploadForAttachment: 通知/SSE/アクティビティを行わない添付専用アップロード(source='attachment') - ChatService/BoardService: fileIds 受理・添付紐付け・履歴/詳細表示・削除クリーンアップ(トランザクション) - API: POST /attachments + chat/board の fileIds 受理 - UI: AttachmentList(画像サムネイル+Lightbox/ダウンロード) + AttachmentPicker(複数アップロード・送信中は送信不可) をチャット/スレッド/コメントに統合 - 添付ファイルは既存の /api/files/[fileId]/download(権限チェック済)で配信
