Add sFRAX as collateral into cUSDTv3 on Ethereum

This proposal offers advantages based on the high liquidity and reliability of FRAX, as well as the opportunity for users to leverage their assets for greater returns. Since the APY of $sFRAX is linked to the U.S. IORB rate, it is expected to provide a stable yield aligned with economic conditions, making it an attractive source of income for users. Additionally, it adds more options for collateral on Compound, helping users diversify their portfolios.
