This makes two changes to fix additional errors in the Review Bot config process. First, the integration config form was still encountering issues with client-side validation of hidden tool options input elements on some versions of Chrome. Instead of going through and making each element disabled, I've changed it to just set `novalidate` on the top-level form. Second, I noticed that there was an error in the JS console when loading the extension configuration page. This was due to the template overriding the `scripts-post` block but not including the block's super, leaving out some necessary JS files. Testing Done: Exercised the extension and integration config pages.
