A tensor request is what a measurement client makes: it wants the raw
frames *and* how long denoising took. Both come from the same
generation, so both belong on the same response. The sibling
``path`` case already asserts this; the file payload did not.

Register the new test in CI and QA test lists.

TestVideoTensorResponse.test_sync_tensor_file_reports_server_timing is absent from tests/integration/test_lists/test-db/ and tests/integration/test_lists/qa/. Add it to the applicable lists.

Coverage summary: Added test coverage for safetensors and pt; coverage is insufficient until registration is added.

2389 - 2401, Add
TestVideoTensorResponse.test_sync_tensor_file_reports_server_timing to the
applicable CI and QA test-list entries under the existing test-list structure,
ensuring both safetensors and pt parameterized coverage is registered without
changing the test implementation.
