perf(engine): Cut database round trips on the step settle and run paths 
Each queue on the data plane handles one message at a time, so every
sequential round trip adds to the time per execution.

- createSteps: move the failed-step test into the INSERT. The test still
  runs as a statement after the execution-row lock, so it sees a failure
  that commits while the insert waits for the lock. 5 round trips become 4.
- step:settled: read hasFailedSteps in parallel with loadStep and
  loadExecution. A failure that lands after the probe still stops
  planning, because createSteps refuses to insert after a failure.
- step:settled: skip refreshLiveStatus when it cannot change the status:
  after the handler finishes the execution, and after it queues steps for
  an execution that is running.
- v1 step data loader: load the execution and its steps in parallel.

Durability and ordering guarantees do not change. One visible effect:
if a branch suspends while another branch queues steps, the execution
can show 'waiting' instead of 'running' until the next settlement. The
engine treats both statuses as live, so only the reporting API sees it.

Webhook -> 3 NoOps: about 12 fewer sequential round trips on the
orchestrator and 3 fewer on the step worker per execution.
