fix: Bulk Insert를 위해 Auction History, Auction Item Option ID 생성 전략을 변경한다

[dev-ant]

📋 상세 설명

• ID 생성전략 (IDENTITY)의 문제로 Auction History insert시 bulk-insert가 아닌 row-by-row insert가 발생해서, 메모리를 많이 차지했다.
• Bulk insert를 위해서 Auction History는 Open API 데이터에서 제공하는 auction_buy_id를 id처럼 사용하고, auction_item_options는 기존의 id drop 후 uuid pk를 추가해주었다.

Pull Request Overview

This PR changes the ID generation strategy for Auction History and Auction Item Option entities to enable bulk insert operations and improve memory efficiency. The main changes include switching from IDENTITY to using auction_buy_id as the primary key for auction history, and replacing numeric IDs with UUID for item options.

• Converts auction_history primary key from auto-generated IDENTITY to use auction_buy_id from Open API
• Changes auction_item_option to use UUID-based primary key instead of IDENTITY
• Implements proper bulk insert with batch processing for better performance
