Integrate Linting and Code Quality Automation

[hcaballero2]

Description

To improve project readability and catch common bugs early, we need to add automated linting and formatting checks to our CI pipeline. This follows the recommendation to enforce a consistent style across the codebase.

Steps to Reproduce

1. Select and configure linting tools (e.g., flake8 for Python backend, ESLint for React frontend).
2. Add a lint step to the Core CI workflow created in Issue 1.
3. Configure the workflow to fail if linting errors are detected.
4. (Optional) Add a step for automated formatting checks (e.g., Black or Prettier)

Expected Behavior

The CI pipeline should provide automated feedback to contributors regarding code style and formatting.

Environment

• Relevant Tools: ESLint, flake8, Black, Prettier
