#Refs #3812.
This PR modifies the safety margin validation process used during moving funds.
It is possible that a wallet may receive deposits just before it changes states to
MovingFunds.It is also possible another wallets in
MovingFundsstate may commit to transfer their funds to it.To avoid a situation where a wallet ends up with additional funds after it has already moved their own funds we must apply a safety margin.
In #3810 we already added a 24-hour safety margin.
In this PR we add a longer 14-days safety margin when the wallet is a target of a moving funds process from another wallet. We also make sure the calculated safety margin is not greater than half of the
movingFundsTimeout, so that a wallet has enough time to finish their moving funds process.
