Fix/Form and Review Page Updates

Currently this PR only holds accessibility fixes.

Accessibility

Navigating the forms flow I came across a few accessibility issues:

1. The form submission loading screen is not announced to Assistive Technologies (AT). Fix: Update the browser title with the loading title text so an AT user knows whats going on
2. The form submission screen is not announced to Assistive Technologies (AT). Fix: also update the browser title as "Confirmation page: FORM_TITLE" (see video for more info)
3. The Next button feels a little unclear what will happen when clicked. AT users are often wary of clicking vague form buttons encase of accidental submissions. Fix: added AT only text (invisible to sighted users) "Next form section"

Note the above involved some content changes.
