Hover over health factor should say that health factor needs to be > 1

Example here:

Text: "Health Factor represent safety of your deposited collateral against the borrowed assets and its underlying value.
If the health factor goes below 1, the liquidation of your collateral might be triggered."

We should also color the health factor number so it's green when above 3, orange when 1.5-3, and red when below 1.5.
