fix(a11y): collapse map attributions and wrap SummaryList columns on small screens

[jessicamcinchak]

From page 61:

Content is lost when resizing the webpage to a smaller viewing dimension. This instance can
be found with the site boundary section of the definition list. The map feature has been
resized however the tooltip provided is covering the user from identifying the boundary of
the location. This issue affects low vision users who are likely to require a smaller window to
progress through the journey as content is affected.
Additionally, due to the change links being covered on the side of the window, part of the
focus highlight is obscured.

Changes:

• Openlayers map attributions are collapsed on screens less than 500px
• Review page SummaryList 3-column layout is collapsed to single column on screens less than 500px ("small" MUI breakpoint), consistent with GOV.UK component behavior
