importlib.reload(dev_api) reset all module-level globals (RESUME_PATH,
SEARCH_PREFS_PATH, etc.) on every digest/interviews test, causing
subsequent monkeypatch.setattr calls in test_dev_api_settings.py to
silently fail — the patched attribute was reset between fixture setup
and the actual HTTP request.
Fix: patch dev_api.DB_PATH directly via monkeypatch, which pytest reverts
cleanly after each test without touching any other module state.
Also sync resume optimizer endpoints to dev-api.py (hyphen variant).
