Fix "My Medical Records" Functionality

[hanson-lam]

In all user tests conducted, people were confused about the "My Medical Records" button (see image below). Since it's a button - the cursor changes when hovering above it - and clicking it does nothing, users get confused about it. To change this, there are primarily two routes we can go:

1. Add another tab (the button is technically a tab to switch between pages within that sub-box on the profile page) so that it's clear that the button switches between tabs. Since there's only one tab right now, namely the medical records tab, this is not immediately clear.

2. Remove the tab functionality completely and just make the medical records button plain text (like a header or such).

@dhuang0212 I think you should take this one since you modified the Tab/Table structure last time!
