Greptile Summary

This PR successfully refactors widget common property handling by introducing a centralized utility function and adds comprehensive integration tests for bulk widget updates.

Key changes:

• Created buildFlatPageLayoutWidgetCommonProperties utility to eliminate duplicate code across widget creation, update, and restore operations
• Refactored page-layout-update.service.ts to use the new utility in three places (widgetsToCreate, widgetsToUpdate, widgetsToRestoreAndUpdate), removing ~60 lines of duplicated logic
• Added integration tests covering widget create, delete, restore, and mixed operation scenarios with snapshot validation
• The refactoring maintains identical behavior while improving code maintainability and DRY principles

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The refactoring is straightforward and well-tested. The new utility function extracts identical logic that was duplicated across three locations, improving maintainability without changing behavior. Comprehensive integration tests with snapshots validate the bulk update operations including edge cases like mixed create/update/restore scenarios.
• No files require special attention
