Update ForeignKey reference in PublishingRecord model and enhance integration app configuration

- Changed ForeignKey reference from 'content.Content' to 'writer.Content' in PublishingRecord model to ensure correct app_label usage.
- Updated IntegrationConfig to use a unique label 'integration_module' to avoid conflicts.
- Added 'lucide-react' dependency to package.json and package-lock.json for improved icon support in the frontend.
- Enhanced Vite configuration to optimize dependency pre-bundling for core React dependencies.
- Added Phase 5 Migration Final Verification and Verification Report documents for comprehensive migration tracking.
