Below-LUP Deposit Fee Has Extreme Values At High Interest Rates

[kmbarry1]

Context: LenderActions.sol#L168

Description: When poolState_.rate is very high, the assessed fee for deposits below the LUP (Lowest Utilized Price) will approach the entirety of the lender's deposit (note the calculation here); eventually, it even surpasses 100%, causing below-LUP deposit attempts to revert due to an underflow. Essentially, below-LUP deposits go from discouraged to impossible when rates in a pool are high. There is also the risk that a lender might not notice the incredibly high penalty and incur an almost total loss by accident.

Recommendation: Consider limiting the maximum below-LUP deposit fee.

Ajna: Maximum deposit fee capped to 10% in ajna-finance/ajna-core@1bf6ae9.
