Pull Request Overview

This PR ensures the GraphQL endpoint isn’t shadowed by static file serving by reordering mounts, adds a corresponding unit test, and updates the template version.

• Moves the StaticFiles mount in app_def.py.jinja below route and middleware setup so API routes take precedence.
• Adds test_When_graphql_route_called__Then_rendered to test_healthcheck.py.jinja to verify the GraphQL UI renders.
• Bumps the _commit field in .copier-answers.yml from v0.0.49 to v0.0.53.

• [nitpick] The use of multiple {% raw %}/{% endraw %} tags throughout this template clutters the file. Consider wrapping the entire test block in a single raw block and only using Jinja conditionals for the GraphQL sections for better readability.

• Instead of creating a new TestClient(app), consider reusing the existing client fixture for consistency with the Swagger test.

• Because the static file mount is now inside the try block, an error in middleware or router setup would prevent static files from serving. Consider placing the mount call after the try/except to guarantee static files are always mounted.
