This PR introduces an indirection between the `PersistentState` used in business logic and the one written to stable memory (in layout version v9). This allows decoupling refactoring the business logic from storage layout migrations. Further, this PR makes sure that all the optionally configurable fields are initialized and serialized with a sensible default. This allows removing a lot of `Option` handling in the future.
