R-518: a press with the local storage absent backs up nothing (never the off-site tier as a stand-in); an agent that flags no primary keeps the first tier

09 §3 decision 156 says the button makes the local copy only.
Test: TestManualRunTiers_NoPrimaryAvailable_BacksUpNothing (red-proved on the previous version).
