gatelock: annotate a fixture param ruff 0.16.8 now flags; TS workflows dispatchable

The ruff bump surfaced one ANN001 in test_window.py. ts-core / web-ui /
ts-config workflows gain workflow_dispatch so a workflow-only change (like the
last commit, which touched no ts_core/** path and therefore never ran) can be
re-verified on demand.
