Background

Our authentication system needed an upgrade to support more secure login methods and improve the user experience. This PR implements JWT-based authentication with proper password hashing.

Changes Made

I've implemented a complete authentication system with the following components:

• Added user registration and login endpoints

• Implemented secure password hashing with bcrypt

• Created JWT token generation and validation

Business Impact

This implementation:

• Increases security by properly storing user credentials

• Enables a better user experience with token-based authentication

• Provides a foundation for future authorization features
