[Victor-Palha]

Evaluate and migrate the runtime environment from Node.js to Bun for the authentication and email services. Bun offers enhanced performance due to its optimized runtime, faster execution, and built-in features like native TypeScript support.

Objectives:

• Replace Node.js runtime with Bun for the specified services.
• Benchmark performance improvements, focusing on response times and resource utilization.
• Ensure compatibility with existing dependencies and libraries used in the services.
• Update the deployment pipelines to support Bun.

Benefits:

• Reduced latency in authentication and email processing.
• Improved server resource efficiency.
• Faster cold starts and better overall runtime performance.
