Execute Workflow Step

Queues a typed workflow step (e.g., SendEmail) for async execution.

• CanStart must be true (all dependency steps completed)

On success, a WorkflowStepActionMessage is queued to the workflow-step-action queue
for processing by the function app. Returns 202 Accepted immediately.
