Enhanced User Validation, Containerization & CI/CD Improvements

[omatheusmesmo]

This pull request introduces several improvements and new features across the backend, frontend, and CI/CD infrastructure, with a focus on enhancing user registration validation, containerization, and workflow efficiency. Key highlights include enforcing password requirements during user registration, adding Docker and docker-compose support for local development, and refining GitHub Actions workflows for more targeted and efficient CI execution.

User Registration & Validation

• Enforced password complexity requirements (uppercase, number, special character) using a new RegisterUserDTO and validation annotations for user registration; updated related service, controller, and tests to use this DTO. [1] [2] [3] [4] [5] [6]
• Added dependency on spring-boot-starter-validation to enable validation annotations.

Containerization & Local Development

• Added Dockerfile for backend and frontend, along with a docker-compose.yml to orchestrate Postgres, backend, and frontend containers, enabling easy local development and deployment. [1] [2] [3] [4] [5]
• Updated backend database configuration to use sensible defaults and environment variables for container compatibility.

CI/CD Workflow Improvements

• Updated backend and frontend GitHub Actions workflows to only trigger on relevant file changes, reducing unnecessary runs, and improved concurrency group naming for clarity. [1] [2]
• Added a new root-level CI workflow to validate repository structure and configuration files.

Scheduled Workflow & Security

• Improved scheduled triage workflow to prevent execution on forked repositories unless manually dispatched, enhancing security and reducing noise. [1] [2]

Testing Enhancements

• Added comprehensive tests to verify password validation logic in user registration and updated service tests to use the new DTO-based flow. [1] [2]
