This PR adds content for the 'bets#show' view page.

This PR does NOT address styling of the page. That will be separate.

Agree with @Clee681's comments above. Quick question - why the move of `number_to_currency` to the view? My impression was that if you are using the `number_to_currency` logic in one view, then it's okay to insert it there. Otherwise, leave it in the helper method to keep it DRY.
