feat(editor): live step status on the graph during runs

Browse source 
Step run events were previously visible only on the run tab.
Operators who triggered a run there and then switched to
the graph tab saw a static graph — the canvas had no idea
something was executing.

Wire the run events through the FlowEditorController so all
three tabs share the same status snapshot:

 - New StepRunStatus enum on the controller
   (idle / running / done / failed / awaiting).
 - controller.stepStatuses exposes the live map.
 - controller.updateStepStatus is called from the run tab's
   event handler — one source of truth, both views read it.
 - FlowCanvas drops its own stepStatuses parameter and
   pulls from the controller instead, so the canvas now
   shows the running pulse + done check + error cross + pause
   icon in each step's header live, in lockstep with the
   step list on the run tab.

When a fresh run starts (controller.running = true) the
status map is cleared so stale events from a previous run
don't paint the new one.
