Async scraping, scrape_logs, and CLI

Background scraping:
- POST /api/scrape returns 202 immediately with run_id; scraping runs async
- GET  /api/scrape-status?run_id=xxx polls for results per venue
- scrape_logs table: per-venue status (running/ok/error), events_saved, error, timestamps

CLI (npm run scrape):
- npm run scrape              — 全会場をスクレイプ、結果を色付きで出力
- npm run scrape liquid-room  — 特定会場のみ
- npm run scrape -- --list    — 登録済み会場一覧を表示
- エラー時は exit code 1 + エラーメッセージを dim 表示

Venues page:
- 最終スクレイプ日時・成否をインラインで表示
- 会場ごとの「更新」ボタンを追加

Bug fix: upsertEvent に description/optional fields のデフォルト値を設定し
better-sqlite3 の "Missing named parameter" エラーを解消
