swarm-grafana: the bao dashboard reads openbao's journal

Browse source 
The bao board was nine metrics panels, so a gap in log delivery looked like
a quiet bao. Three panels read the log store for openbao.service: lines
delivered over time, WARN and ERROR lines over time, and the recent WARN and
ERROR lines themselves. A module-eval case pins them by query.
