ManagedLeveragedVault::increaseLeverage() will never work in Recovery mode

Summary

Recovery mode doesn't allow Dens to decrease their ICR. Hence, ManagedLeveragedVault::increaseLeverage() will revert when the protocol is in Recovery mode.

Vulnerability Detail

ManagedLeveragedVault::increaseLeverage() withdraws debt:

b$.borrowerOperations.withdrawDebt(
    b$.denManager,
    address(this),
    _maxFeePercentage,
    _debtAmount,
    _upperHint,
    _lowerHint
);

But this is not possible in Recovery mode, as it requires that the new ICR is bigger than the old one.

Impact

DoSed increasing leverage.
