Peter/loans fix subsidy rewards

[peterslany]

Description

Closes #1265

• Accrued subsidy reward computation is fixed to display correct amount - update on the lib side (2.3.1)
• Per market partial reward is hidden because of not being able to estimate it correctly on per market basis in straightforward way
• Loans net APY computation verified - calculation is correct

Before - Rewards tooltip showing partial reward which is incorrect

After - Rewards tooltip shows only APY (note that total reward is still shown on top of the page)
