fix(webapp): read the span-panel waitpoint from the owning store

SpanPresenter built WaitpointPresenter with no run-ops read clients, so the trace
panel read a NEW-residency waitpoint on the control-plane database and showed
"Waitpoint not found". Wire the run-ops read clients like the other split-aware
routes.
