chore: Add GitHub workflows for JavaScript and Python autofix

This commit adds GitHub workflows for JavaScript and Python autofix. The JavaScript workflow is triggered on pull requests and pushes to the main branch, specifically for changes in the "src/frontend" directory. It checks out the code, sets up Node.js, caches Node.js dependencies, installs Node.js dependencies, and runs Prettier for code formatting. The Python workflow is also triggered on pull requests and pushes to the main branch, but for changes in the "poetry.lock", "pyproject.toml", "src/backend", and "tests" directories. It checks out the code, installs Ruff, and runs Mypy for type checking and code formatting.
