Record domain transaction for DomainRestoreFlow

This is the first of many cls adding explicit logging in all our domain mutation flows to facilitate transaction reporting.

Restores are relatively simple- it happens immediately, so the reporting time is just the time of the HistoryEntry, and we add a single "RESTORED_DOMAINS" count of 1.
