 P-Chain until it runs out. To prevent the balance from running out, and validation pausing, any validator can increase its balance with
 `IncreaseL1ValidatorBalanceTx`. If a validator decides to end its validation with `DisableL1ValidatorTx`, any remaining balance that has not
 been used to pay the continuous fee will be returned.
