Calculate and display total savings by highest bid

[mtorres253]

We should offer a variety of ways to look at the total savings number, so that people can have a fuller picture of this metric, we should measure savings by highest bid (maximum possible award) to lowest bid (winning award)

• Create metric for total savings by bid: (Sum of highest bids for each successful auction) - (Sum of lowest bids for each successful auction)

• "Savings calculation is based on start price" indicator

• Implement toggle between two savings numbers (savings based on start price and savings based on highest bid)

Adding the explaination of the calculation and the toggle between the two calculations.

Updated screenshots to include tabs instead of a 🔄 for the toggle interaction.
