An array of integers is now used to represent the SRP in three cases: * In the import wallet flow, the UI uses it to pass the user-provided SRP to the background (which converts the array to a buffer). * In the create wallet flow, the UI uses it to retrieve the generated SRP from the background. * When persisting the wallet to state, the background uses it to serialize the SRP.
