CDClientSnapshot converts a copy of the client's fdb into its own CDServer-<hash>.sqlite with the cdserver migrations applied, on its own connection. CDClientDatabase::Reconnect opens the new file before letting go of the old one; CDClientManager::Reload empties every table (old entries kept alive so references from spawned objects stay valid), retires the old fdb view and loads again.
