Adjust the Web Mobile views of Ground to display on mobile viewports

**Describe the bug**
On a mobile phone viewport, the website is displaying the content of the About screen and the Terms of Service screen in a very narrow vertical strip, making it hard for the user to read.

**To Reproduce**
Steps to reproduce the behavior:
1. On a mobile viewport (I tried on a Galaxy S13) go to the website
2. Click on the About link in the 'i' icon (top right), or once signed in click on the Terms of Service link from the same menu.

**Expected behavior**
Contents should maximize the horizontal width, making the text readable

**Actual behavior**
The body of text is shown in a very narrow strip, or in the case of the Terms of Service a very small box, making it practically unreadable.

Note it looks good in the Android app, and on web.
