test: pin read_window_below into the toolset + post-hook contracts, appease eslint

The desktop_ui and post-hook ownership contract tests enumerate their tool
sets exactly — add read_window_below to both (plus the executor-path
parametrize case). Lint: sorted type import, explicit GetWindowsModule type
instead of an import() annotation, curly + blank-line style.
