Implement global stilying for unordered lists

On EdEhrOrgAbout.vue, we currently need to manually reset the ul element's font-size to 18px, for reasons we do not fully understand yet. You should look into that a bit more and try to understand what is conflicting with the ul styles, causing it to behave this way.

The task at hand is to simplify styling to ul elements in the app in an effort to make them more predictable by adding it into global styles for all elements in the app.

Before making your PR, please, make sure that no unordered list element in the app are broken and that the styles are being applied to all of them consistently.
