Deploy TypeScript notice board to AWS - Gervonte Fowler

[Gervonte]

Summary

• adapt the existing React, TypeScript, Express, and MongoDB project into a notice board with list, create, and delete flows
• package the Express API for the supported Node.js 24 Lambda runtime
• provision API Gateway, Lambda, private S3 hosting, CloudFront OAC, IAM-role input, and bounded CloudWatch logs with Terraform
• add a path-scoped GitHub Actions deployment workflow for the Gervonte/workshops fork
• document local development, manual deployment, GitHub secrets, networking, and cleanup

Assignment approach

This implementation keeps the existing TypeScript backend rather than replacing it with the Python starter. It preserves the assignment architecture and deployment outcomes: browser to CloudFront/S3, API Gateway to Lambda, and MongoDB persistence.

The root workflow is guarded to run only in Gervonte/workshops, so the upstream pull request cannot use the fork's AWS secrets.
