[Closes #114, #122] Add checkmark to viewed patient registration form sections

[samau3]

Closes #114, closes #122.

This PR adds a checkmark icon as feedback for the user to see which sections have been viewed/completed and displays the select field options in a more readable format.

• Utilizes conditional rendering to show a check mark for viewed sections
• Paired with the form submission feedback, the user can more easily identify which sections need to be reviewed to submit the registration form
• Converts the enumerated values shown on the form select fields to be in title casing
• Also resolved bug with being unable to change healthcare choices due to not properly updating input field values

I'm going to approve and merge this in to close #114, although I think we can do more with #122...
