Subject: [PATCH 1/8] test(backend): add workflow run/delete race and
 disabled-workflow coverage

Closes #570

- Tests for DELETE during active run
- Tests for toggle/disable during run
- Tests disabled workflow leaves DB unchanged
- Tests concurrency limiter marks tasks failed when full
- All tests are deterministic, no live DB required

Subject: [PATCH 5/8] test(backend): rewrite workflow race/disabled tests to
 call real routes

Remove FakeDB/FakeExecutor/WorkflowRunner stubs. All tests now use
TestClient against the real route handlers in routes.py with
unittest.mock.patch at the db boundary only.

- TestDeleteThenRunRace: patches db.fetchone to return None, asserts
  real route returns 404 (not a crash or orphaned task)
- TestDisabledWorkflow: patches db.fetchone with enabled=0 row, asserts
  real route refuses run with 400/409; list route surfaces enabled=False;
  PUT toggle calls real db.execute
- TestDeleteThenList: patches db.fetchall, asserts list is empty or
  shows only remaining workflows after deletion
- TestEnabledWorkflowRun: patches db layer, asserts enabled workflow
  run returns 200 with workflow_id in body

No production files modified.

Closes #570

 Regression tests for workflow run/delete race conditions and
 disabled-workflow behaviour as described in issue #570.
 
 Strategy
 --------
 All tests call the REAL application routes through TestClient.
-The database layer (db.fetchone / db.execute / db.fetchall) is patched
-with unittest.mock so no live SQLite file is needed, but the production
-route handler code in routes.py runs unchanged.
+``backend.secuscan.routes.get_db`` is patched with a plain async function
+that returns a controlled mock, matching the ``db = await get_db()`` call
+shape used in routes.py.  No live SQLite file is needed and results are
+fully deterministic in CI.

-All tests call the REAL application routes through TestClient.
-``backend.secuscan.routes.get_db`` is patched with a plain async function
-that returns a controlled mock, matching the ``db = await get_db()`` call
-shape used in routes.py.  No live SQLite file is needed and results are
-fully deterministic in CI.
+All tests call the REAL application routes through the shared ``test_client``
+fixture defined in conftest.py, which initialises the real database, plugins,
+and auth layer.  ``backend.secuscan.routes.get_db`` is patched with a plain
+async function returning a controlled mock, matching the
+``db = await get_db()`` call shape used in routes.py, so no persistent
+SQLite state leaks between tests.
