Fix GraphQL enrichment to use displayId instead of numeric lotId

- Added displayId (String) field to Lot record for full lot ID (e.g., "A1-34732-49")
- Updated ScraperDataAdapter to extract both numeric ID and displayId from database
- Fixed TroostwijkGraphQLClient to query by displayId using lotDetails() instead of lot()
- Matched Python scraper's query structure with LOT_BIDDING_QUERY pattern
- Updated GraphQL response parsing to handle lotDetails.location and biddingStatistics
- Added upsertLotWithIntelligence() method to DatabaseService for full intelligence updates
- Updated LotEnrichmentService to pass displayId to GraphQL client

This fixes the "No intelligence data returned" error on production server.
GraphQL API requires string displayId parameter, not numeric lot ID.
