feat(web-test): multi-select rows with modifier + _selected in readTable

Add modifier option ('ctrl'|'shift') to clickElement for Ctrl+click
(add to selection) and Shift+click (select range) in grid rows.
Add _selected: true flag to readTable rows so the model can verify
which rows are currently selected before performing actions.
