fix: Q64 scored a point for doing nothing; Q45 failed a grade taken right after the restore

Browse Source 
Q64's "nothing was created in namespace default" check was a bare negation,
so an untouched task scored 1/6. It now requires the Deployment to exist in
the context's namespace first.

Right after an etcd restore the API still holds the snapshot's mirror pods
and the kubelet replaces them; a grade inside that window found etcd's pod
missing and failed the health check, 8/10 for a correct restore. The check
now retries for up to a minute.

Re-verified on a throwaway cluster: both score 0 untouched and full when
solved, Q45 graded immediately after the restore.
