Plugins: Prevent `ajaxComplete` listener from observing all events.

Add a conditional to prevent the `prefers-reduced-motion` `ajaxComplete` listener from observing events not occurring in the plugin installation screen. Improve handling of settings data test.

The listener observing `ajaxComplete` in [56541] was intercepting all `ajaxComplete` events, creating potential for unexpected errors in unrelated functions.

Fixes #59689.
