Description Of Changes

This is a small CSS change to ensure the overall app layout is consistent between the Fides and Fides Plus Admin UIs. In the Plus UI we have some pages that need to fill the viewport height, so the overall Layout needs to include height=100vh over there - by doing the same here, it just means we're less likely to get some minor discrepancies in app layouts over time without noticing.

Note: this should have no visual effect on the existing app pages! I looked at all of them (home, privacy requests, data map, management) and confirmed this... it might seem like a useless PR but I promise this makes sense 😛
