The scraper uses TEXT IDs like "A7-40063-2" but DatabaseService was creating
BIGINT columns, causing PRIMARY KEY constraint failures on the server.
Changes:
- auction_id: BIGINT -> TEXT PRIMARY KEY
- lot_id: BIGINT -> TEXT PRIMARY KEY
- sale_id: BIGINT -> TEXT
- Added UNIQUE constraints on URLs
- Added migration script (fix-schema.sql)
This fixes the "UNIQUE constraint failed: auctions.auction_id" errors
and allows bid data to populate correctly on the server.
