Clearing

Clearing
Abstract implementation of the clearing module's global state and account-level reads.
Implements the one-shot initializer, the activation lifecycle and the account-scoped read queries on top of ClearingStorageWrapper and ClearingReadOps. The activation toggles enforce the onlyUnpaused and onlyRole(ROLE_CLEARING) guards; initializeClearing is gated by onlyRole(DEFAULT_ADMIN_ROLE) + onlyFacetNotRegistered. by ClearingFacet.
