Revert ENJ Parameter Changes and Enable FEI as Collateral on Aave V2

The proposal describes two actions: reverting ENJ's collateral parameters to their pre-AIP-55 values and enabling FEI as collateral with LTV 50%, liquidation threshold 60%, and liquidation bonus 6.5%. The decoded calldata contains exactly two configureReserveAsCollateral calls on the same LendingPoolConfigurator contract. Action 0 targets the ENJ token address and sets LTV 60%, liquidation threshold 70%, and a bonus value of 10750 (which represents a 7.5% liquidation bonus, consistent with typical pre-AIP-55 ENJ parameters described as being reverted). Action 1 targets the FEI token address and sets LTV 50%, liquidation threshold 60%, and bonus 10650 (6.5% bonus), which matches the description's stated FEI parameters exactly. The contract address in the Implementation section has an extra hex character (41 vs 40 chars) compared to the actual calldata target, but this is a trivial documentation typo that does not change the actual on-chain target, which is verified to be the correct LendingPoolConfigurator address in both actions. No value, target, or scope discrepancies were found between the prose and the calldata.'
