Fixed field name mismatches for tables with lastUpdatedUTC (all-caps):
- IV_Product: lastUpdateUtc → lastUpdatedUTC
- Department: lastUpdateUtc → lastUpdatedUTC
These field names must match the Prisma schema exactly (case-sensitive).
Ensures smart sync decision logic can correctly probe for record updates.
