Pull Request Overview
This PR establishes shared AWS infrastructure using Terraform and implements a user service as the first microservice. The infrastructure includes VPC, networking, Application Load Balancer, and RDS PostgreSQL, along with a complete Go-based user service with ECS deployment and auto-scaling capabilities.
- Sets up core shared infrastructure (VPC, ALB, RDS PostgreSQL) in modular Terraform
- Implements user-service with CRUD operations, database schema initialization, and containerized deployment
- Adds test data generation scripts and team coordination documentation

Hardcoded default password 'changeme123!' is a security risk. Remove the default value and require this to be provided via environment variable, tfvars file, or AWS Secrets Manager to prevent accidental deployment with weak credentials.

AWS provider version constraint '> 6.7.0' conflicts with the root terraform configuration which uses '> 5.0'. Use consistent provider versions across all modules. Consider using '~> 5.0' to match the root configuration or update both to use the same major version.

SQL injection vulnerability: database name is concatenated directly into SQL query. While dbName comes from environment variables, use identifier quoting with pq.QuoteIdentifier() or validate dbName against a strict pattern (alphanumeric and underscores only) to prevent SQL injection.

SQL injection vulnerability and password exposure: both serviceUser and masterPassword are concatenated directly into SQL query. Use pq.QuoteIdentifier() for the username and parameterized queries or proper escaping for the password. Additionally, the password is logged in plain text in the query string if there's an error.

| # Shared RDS Aurora Cluster |

Comment says 'Shared RDS Aurora Cluster' but the actual implementation in modules/rds/main.tf creates a single RDS PostgreSQL instance (aws_db_instance), not an Aurora cluster. Update the comment to 'Shared RDS PostgreSQL Instance' to accurately reflect the implementation.

Incorrect return value: the function always returns the last error value instead of nil on success. Change to 'return nil' since any actual error would have been returned earlier at line 192.
