Replace AWS Deployment with LocalStack for Local Development and Testing

[vovanduc]

Feature Request

Currently, the deployment is being done on AWS. However, to facilitate testing and development, I would like to replace this deployment with LocalStack on the local environment.

I want the current configuration and deployment parts of the project to be changed from AWS to LocalStack. This includes:

• Using LocalStack services instead of AWS (e.g., S3, DynamoDB, Lambda, etc.)
• Updating configuration files to connect to LocalStack
• Adding deployment and testing instructions with LocalStack to the project documentation

Thanks!
