Pull Request Overview

This PR introduces a comprehensive Prisma schema configuration that establishes multi-database support for AWS S3, PostgreSQL, MongoDB, and AstraDB. The implementation provides a unified data layer architecture with specialized models for each database type while maintaining cross-database compatibility.

Key changes include:

• Multi-database datasource configuration with PostgreSQL as primary, MongoDB for documents, and AstraDB for distributed data
• Database-specific models optimized for each platform's strengths (relational for PostgreSQL, document-based for MongoDB)
• AWS S3 file metadata management system with processing job tracking
• Universal models and monitoring capabilities for cross-database operations
