Update UX of Settings Page

[kevinfodness]

Description

A recent WordPress update broke the display of the settings page, and it needs to be corrected.

Acceptance Criteria

• Update the display of the settings page (Settings > SEO) so that it uses current WordPress classes/standards, properly depends on the styles and scripts that need to be enqueued in order for it to work (we were likely assuming particular CSS and JS would always be enqueued and they may not be any longer in new versions of WP), and otherwise looks like the settings page should.
• Refactor out the use of jQuery on this page.

Use Case

A user utilizing the settings page should get a UI that doesn't look broken.
