feat: get user

[daniloamsilva]

This pull request introduces a new authenticated endpoint for retrieving the current user's details and implements supporting infrastructure for authentication using JWT. It also adds corresponding controller, service, and tests, and improves test reliability.

Authentication infrastructure:

• Added a global AuthGuard using JWT to secure endpoints by default, with support for public routes via metadata. (src/application/shared/guards/auth.guard.ts, src/app.module.ts) [1] [2] [3]
• Introduced a Payload decorator to easily access the JWT payload in controllers. (src/application/shared/decorators/payload.decorator.ts)

User endpoint and logic:

• Added a new GET /users/me endpoint via GetUserController to return the currently authenticated user's details, using the new GetUserService. (src/application/users/controllers/get-user.controller.ts, src/application/users/services/get-user.service.ts, src/application/users/users.module.ts) [1] [2] [3] [4]
• Implemented a toJSON method on the User entity to exclude sensitive fields like password and tokens from API responses. (src/domain/users/entities/user.entity.ts)

Testing improvements:

• Added integration and unit tests for the new endpoint and service, covering both successful and failure scenarios. (tests/integration/application/users/controllers/get-user.controller.test.ts, tests/unit/application/users/services/get-user.service.test.ts) [1] [2]

Other improvements:

• Modified the Jest test script to run tests sequentially for improved reliability. (package.json)

Pull request overview

This PR introduces a new authenticated endpoint for retrieving the current user's details (GET /users/me) and implements the necessary JWT-based authentication infrastructure to secure endpoints globally. The implementation follows domain-driven design principles with proper separation between controllers, services, and domain entities.

Key changes:

• Added a global AuthGuard that secures all endpoints by default using JWT authentication, with support for marking routes as public
• Implemented GET /users/me endpoint with corresponding service layer and domain method to safely serialize user data
• Enhanced test reliability by running Jest tests sequentially
