Update PageLayout interface

[maloky]

What are you doing in this PR?

Make PageLayout borderBox prop mandatory. Fix an issue where the NavLink on the thank you page overlap with the cards if the cards hit the bottom of the page.

Trello Card

Why are you doing this?

We want to explicitly set this prop so we don't run into unexpected page layout behaviours due to refactor side effects.

How to test

How can we measure success?

Have we considered potential risks?

Accessibility test checklist

• [ ] Tested with screen reader
• [ ] Navigable with keyboard
• [ ] Colour contrast passed
• [ ] The change doesn't use only colour to convey meaning
