Extract the restore_command object-store selection out of Restore into a
pure resolveRestoreObjectStore helper and add table-driven coverage for
the routing decision, including the designated-primary promotion case
(both switchover and failover) that previously had no regression test.
The refactor is behavior-preserving; it also makes the gocognit
suppression on Restore unnecessary, so it is dropped.
