Adding 'bets#show' content

This PR adds content for the 'bets#show' view page.

This PR does NOT address styling of the page. That will be separate.

cc @Clee681 @irmiller22 LMK what you think please
The reason why this is here is because we only wanted to change the `<body>` element's background color when this view is rendered. Although, there may be a better way to do this. Any thoughts on how to do it?
