Add more details about Balanced positions

We could include another section on the Stats page to display the health of positions on Balanced.

• Current collateral/LTV ratios (highest, lowest, average for platform)
• Price when the first positions will be liquidated
• Bad debt (if any)
• ?

This info would help to inform decisions about adjusting the LTV ratio, and will be interesting to monitor in general.
