fix(website-crawler): Add missing crawl_status column to SELECT query

Fix the SQL query in check_and_crawl_websites() to also include crawl_status
in the SELECT clause. The WebsiteCrawlRecord struct expects this field but it was
only present in the WHERE clause, causing Diesel to fail with
'Column crawl_status was not present in query'.

This resolves the second website crawler service error.
