Refs #34995 -- Made Selenium tests more robust for admin_views and admin_widgets suites.

Depending on screen sizes, the selenium tests that would "click" or interact
with an element outside the scope of the visible window would produce test
failures (raising ElementNotInteractableException in CI runs).

This branch switches those to using ActionChains, which ensures that the click
(or other interaction) is performed only after successfully completing the
move to the relevant element.
