Fix TOS page jump to bottom.

[P-Gill97]

The issue is due to the browser autofocusing to the checkbox which causes the browser to scroll when the policy is longer than a page. I tried updating the checkbox line here <%= f.check_box :i_agree, style: "height: 1.3rem"%> by adding the attribute for autofocus: false. It did not work and the page kept jumping down to the bottom. So instead I added an DOMContentLoaded event listener document.addEventListener("DOMContentLoaded", function() { and set the window scroll to the top of the page using window.scrollTo(0, 0);. This is my first time working on accounts and working with Ruby so let me know if there is something obvious I am missing.

I am worried that this will cause the page to flash different positions when loading?
Also wondering if the second thing mentioned in the card (the button not being visually disabled) has been fixed already or if it's still an issue.
