Add a status column to the security dashboards

Problem to solve

In the run-up to #13561 (closed) we need to make a handful of tweaks to the current security dashboards.

This change introduces a "Status" column. Once the backend is in place, we will have access to a "status" value on the vulnerability object. We need to display that status as-per the design below.

However, that "Status" isn't in the data yet and won't always be for different dashboards so we need to conditionally hide that column if the data isn't there.

Documentation

Since this change will be hidden for now, no documentation should be required as no one will be able to see the change.
