backend/tests/integration/test_static_html_cache_headers.py asserted
that "/", "/spoolbuddy/", and "/printers" return text/html with
Cache-Control: no-cache, must-revalidate. The Dockerfile.test
backend-test target intentionally doesn't bake in the built frontend
(saves ~30s of build time per test run), so static/index.html doesn't
exist inside the container. The route handlers correctly fall through
to their "frontend not built" JSON branches, and the test fails with
"non-HTML content-type: application/json" — latent since the test was
added in e9200449 (Apr 26).
Add a fake_static_index fixture that creates a tmp dir with a one-line
<!doctype html> stub and monkeypatches app_settings.static_dir to it.
Both call sites are patched (config.settings and main.app_settings) in
case a future refactor splits the singleton. The test continues to hit
the real serve_frontend / serve_spa route handlers and validates the
real cache-header contract — just doesn't depend on a built bundle
being present.
Verified passing both with and without static/index.html present.
