HEAL2 (the healers' findings in requires): the manifest test holds the state and the stream asked by their templates

The healers' manifest already asks findings (template state) and finding-events (template events, the three finding events,
7 days, 16 MiB) and declares no old stream or findings state, and their writer reaches the state by its local name (built in
76be864b and the join); this adds the test that holds it.

Builds: design 47 G §529, §577, A-30
